I have ImageButton Inside ItemTemplate in GridView I want to change Image Url "Image source" based on condition that I have prepared before. In short when I click on the ImageButton, change it's image source "For the imageButton" based on the condition I have. Here is the code I have below:
ASP.NET GridView code:
<asp:GridView ID="GridView1" BorderStyle="None" GridLines="None" runat="server" AutoGenerateColumns="False" DataSourceID="SqlDataSource1">
<Columns>
<asp:BoundField DataField="photo_id" HeaderText="photo_id" InsertVisible="False" ReadOnly="True" SortExpression="photo_id" ItemStyle-CssClass="hiddencol" HeaderStyle-CssClass="hiddencol"/>
<asp:TemplateField HeaderText="photo_path" SortExpression="photo_path">
<EditItemTemplate>
<asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("photo_path") %>'></asp:TextBox>
</EditItemTemplate>
<ItemTemplate>
<div class="container-md">
<div class="container">
<asp:Image ID="Image8" runat="server" ImageUrl='<%# Eval("photo_path") %>' CssClass="mx-auto d-block - responsive"/>
<div class="centered">
<asp:ImageButton ID="img_like" CssClass="os" runat="server" ImageUrl="~/images/like.png" OnClick="img_like_Click"></asp:ImageButton>
</div>
</div>
</div>
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="user_id" HeaderText="user_id" SortExpression="user_id" ItemStyle-CssClass="hiddencol" HeaderStyle-CssClass="hiddencol"/>
<asp:BoundField DataField="photo_likes" HeaderText="photo_likes" SortExpression="photo_likes" ItemStyle-CssClass="hiddencol" HeaderStyle-CssClass="hiddencol"/>
</Columns>
</asp:GridView>
Code Behind "C#" With the If Statement condition:
protected void img_like_Click(object sender, ImageClickEventArgs e)
{
ImageButton btn = (ImageButton)sender;
GridViewRow gvr = (GridViewRow)btn.NamingContainer;
if (isPhotoLiked(Convert.ToInt32(gvr.Cells[0])))
{
// CHANGE IMAGE TO FILLED HEART IF TRUE
} else
{
// CHANGE IMAGE TO EMPTY HEART IF FALSE
}
}
The method that generates the condition if you need it:
public bool isPhotoLiked(int photoId)
{
bool isLiked = false;
SqlConnection con = new SqlConnection("server=DESKTOP-N1LLATD\\SQLEXPRESS;database=final;integrated security=sspi");
string sql = "select isLiked from Likes where photo_id=#photo_id";
SqlCommand cmd_add = new SqlCommand(sql, con);
cmd_add.Parameters.AddWithValue("#photo_id", photoId);
SqlDataReader read;
con.Open();
read = cmd_add.ExecuteReader();
if (read.HasRows)
{
if (read.Read())
{
isLiked = Convert.ToBoolean(read["isLiked"].ToString());
con.Close();
}
}
return isLiked;

I want to read the gridview column data in c#.
I am using C# as a backend and ASP.Net as backend.

SqlCommand cmd;
int rowindex = Convert.ToInt32(e.CommandArgument);
GridViewRow SelectedRow = GridView2.Rows[rowindex];
string id = Convert.ToString(GridView2.DataKeys[rowindex].Values[0]);
string team_name = SelectedRow.Cells[4].Text;

{
if (team_name == "null")
{
Label3.Text = "Team name cant be blank";
Label3.Visible = true;
}
}
}
}
How to get the team name from the gridview?
I am unable to get data from column 4: SelectedRow.Cells[4].Text;
Team name holds in a textbox control of column 4. so, select team text control and you should get team name as text property of text box. Change code like this:
int rowindex = Convert.ToInt32(e.CommandArgument);
GridViewRow SelectedRow = GridView2.Rows[rowindex];
string id = Convert.ToString(GridView2.DataKeys[rowindex].Values[0]);
TextBox txtteam= (TextBox)SelectedRow.Cells[4].FindControl("TextBox");
string team_name = txtteam.Text;
//= Convert.ToString(GridView2.Rows[rowindex].Values[4]);
Response.Write(team_name + "what the hell it is" + SelectedRow.Cells[0].Text + SelectedRow.Cells[1].Text + SelectedRow.Cells[2].Text + SelectedRow.Cells[3].Text + txtteam.Text);
if (e.CommandName == "participate")
{
if (team_name == "null")
{
Label3.Text = "Team name cant be blank";
Label3.Visible = true;
}
}
I have a GridView that lists data from my mysql database table. In addition, I created two TemplateFields to the GridView. The first TemplateField displays the data from database tables and the second TemplateView contains 1x asp:TextBox (a.k.a quantity) and 2x asp:Buttons (a.k.a +/- buttons which change the value inside the quantity TextBox. In addition to binding the GridView on PageLoad event, I also have a search TextBox which filters the rows displayed in the GridView. Here is the code behind for the search GridView TextBox:
private void SearchProducts()
{
string constr = ConfigurationManager.ConnectionStrings["default"].ConnectionString;
using (MySqlConnection con = new MySqlConnection(constr))
{
using (MySqlCommand cmd = new MySqlCommand())
{
string sql = "SELECT logic_code,description,image_location,product_group,supplier_number,sequence,unit_code,unit_of_price,location,sales_date,price_pref,special_price,in_stock,total_inventory,new_products FROM products";
if (!string.IsNullOrEmpty(txtSearch.Text.Trim()))
{
sql += " WHERE description LIKE " + "'%" + txtSearch.Text + "%'";
}
cmd.CommandText = sql;
cmd.Connection = con;
using (MySqlDataAdapter sda = new MySqlDataAdapter(cmd))
{
DataTable dt = new DataTable();
sda.Fill(dt);
GridView1.DataSource = dt;
dt.Columns.Add(new DataColumn("QUANTITY"));
GridView1.DataBind();
//TextBox qty4 = GridView1.FindControl("qty_ordered") as TextBox;
// for(int i = 0; i < GridView1.Rows.Count; i++)
//{
// Label test222 = (Label)GridView1.Rows[i].FindControl("test2");
// TextBox qty2 = (TextBox)GridView1.Rows[i].FindControl("qty_ordered");
// if (ViewState["purchased"] != null)
// {
// qty2.Text = ViewState["purchased"].ToString();
// }
// //test222.Text = qty2.Text;
//}
}
}
}
//foreach(GridViewRow rows in GridView1.Rows)
{
//Label test22 = rows.FindControl("test2") as Label;
//TextBox qty = rows.FindControl("qty_ordered") as TextBox;
//if (ViewState["purchased"] != null)
//{
//qty.Text = ViewState["purchased"].ToString();
//}
}
}
First I tried saving each Rows TextBox.Text to ViewState but wasn't successful, then I tried dynamically adding a new column to DataTable before DataBind() but that also went south... The Buttons (+/-) and TextBox work fine when PostBack is from the buttons themselves. However, as soon as I filter the GridView using the c# code above, The TextBoxes all turn back to "0" and lose their values. I think that adding the new column dynamically is the way to go, I'm just not sure how to save/update the values without creating EditTemplateFields.
Here is my asp.net code for the GridView:
<asp:GridView id="GridView1" EnableViewState="true" AutoGenerateColumns="false" PageSize="100" ShowHeader="false" DataKeyNames="logic_code" AllowPaging="true" runat="server" Style="width:100%;margin-top:45px;">

<asp:Label id="test2" runat="server" Visible="true" Enabled="false" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
Here is the code behind for how I populate the GridView on PageLoad when the GridView is not getting filtered by the search box:
private void BindGrid()
{
string constr = ConfigurationManager.ConnectionStrings["default"].ConnectionString;
using (MySqlConnection con = new MySqlConnection(constr))
{
con.Open();
using (MySqlCommand cmd = new MySqlCommand("SELECT logic_code,description,image_location,product_group,supplier_number,sequence,unit_code,unit_of_price,location,sales_date,price_pref,special_price,in_stock,total_inventory,new_products FROM products"))
{
using (MySqlDataAdapter da = new MySqlDataAdapter())
{
cmd.Connection = con;
da.SelectCommand = cmd;
using (DataTable dt = new DataTable())
{
da.Fill(dt);
GridView1.DataSource = dt;
dt.Columns.Add(new DataColumn("QUANTITY", System.Type.GetType("System.Double")));
GridView1.DataBind();
con.Close();
}
}
}
}
}
And PageLoad is here:
protected void Page_Load(object sender, EventArgs e)
{
if (!this.IsPostBack)
{
BindGrid();
}
if (string.IsNullOrEmpty(txtSearch.Text))
{
//txtSearch.Attributes.Add("CssStyle", "cursor");
txtSearch.Attributes.Add("placeholder", " Showing All Products");
}
//foreach(GridViewRow row in GridView1.Rows)
//{
// if (IsPostBack)
// {
// if (ViewState["purchased"].ToString() != null)
// {
// qty.Text = ViewState["purchased"].ToString();
// }
// }
//}
}
I also have EnableViewState = "true" at the top of page.
***Note: with the code below on each button (+/-), the ViewState seems to save fine as my labels get populated appropriately by reading the ViewState even when postback. However, the values of the labels (ViewState value) get reset once I call the private void SearchProducts()
for(int i = 0; i < GridView1.Rows.Count; i++)
{
Label test222 = (Label)GridView1.Rows[i].FindControl("test2");
TextBox qty2 = (TextBox)GridView1.Rows[i].FindControl("qty_ordered");
ViewState["purchased"] = qty2.Text;
test222.Text = ViewState["purchased"].ToString();
}
and heres 2 snapshots: (as you can see, when I enter "Benus" inside the search textbox, the gridview gets filtered correctly, but all the TextBox values gets reset to "0")
I have a nested GridView with 4 levels,
when i click in "+" to show child GridView i make request to database to download data of current row, every thing work well for me, the only problem i have is in design, all the child GridView display in column of its parent GridView

I just want that only selected row should be affected in database.
I will be thank full for help.
you need to set the id_company_user value in your sql statement. use parameters as below.
SqlCommand cmd = new SqlCommand("update ref_registration_company_user set ind_active=1 where id_company_user=#id_company_user", conn);
cmd.Parameters.AddWithValue("#id_company_user", id);
you need to get current row id_company_user value check below SO question and answer, you can use
OnRowCommand of GridView and CommandArgument property
GridView: Get datakey of the row on button click
<asp:GridView ID="grdCompanyUsers" runat="server" DataKeyNames="id_company_user,nm_company_username" AutoGenerateColumns="false" GridLines="None" CssClass="grid" AlternatingRowStyle-BackColor="#DDE0EF" OnRowDataBound="grdCompanyUsers_DataBound"

cmd.Parameters.AddWithValue("#id_company_user", id);
cmd.ExecuteNonQuery();
}
}
}
Can you please check once your update query where clause,
Check the sqlDataSource control for this problem, you can add the select and update command for populate and update rows your GridView on there.
Maybe this example could be you useful
http://asp-net-example.blogspot.mx/2008/12/aspnet-gridview-and-sqldatasource.html
I have the following database design:
Employee Table: Username, Name, JobTitle, BadgeNo, IsActive, DivisionCode
Divisions Table: SapCode, DivisionShortcut
And I have a GridView that I am using it to add, delete and update/edit the employees information. This information is employee Username, Name, BadgeNo, JobTitle, IsActive and the DivisionShortcut. IsActive is a flag that indicates if the employee is available or in an assignment. I made it as a checkbox and the column should show two values; Active and Inactive. In the Edit mode, the Checkbox will be displayed. If it is checked, then it means the employee is avaiable, otherwise it is inactive.
I wrote the code and everything works fine, but now I am facing only one problem which is the following: when the checkbox is unchecked that means the employee is inactive, so I want the row that shows his information to be in a grey color (like disabled).
So how to do that?

Code-behind:
//for updating the (IsActive) column using checkbox inside the GridView
protected void isActive_OnCheckedChanged(object sender, EventArgs e)
{
CheckBox chkStatus = (CheckBox)sender;
GridViewRow gvrow = (GridViewRow)chkStatus.NamingContainer;
//Get the ID which is the NetworkID of the employee
string username = gvrow.Cells[2].Text;
bool status = chkStatus.Checked;
string connString = ConfigurationManager.ConnectionStrings["UsersInfoDBConnectionString"].ConnectionString;
SqlConnection conn = new SqlConnection(connString);
string updateIsActive = "UPDATE Employee SET IsActive = #IsActive WHERE Username = #Username";
SqlCommand cmd = new SqlCommand(updateIsActive, conn);
cmd.Parameters.AddWithValue("#IsActive", status);
cmd.Parameters.AddWithValue("#Username", username);
try
{
conn.Open();
cmd.ExecuteNonQuery();
conn.Close();
}
catch (SqlException se)
{
throw se;
}
finally
{
cmd.Dispose();
conn.Close();
conn.Dispose();
}
}
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
// First check Checkedbox is check or not, In Cells insert you IsActive column index
if( e.Row.Cells[1].Text == "False" )
GridView1.BackColor = Color.Gray;
}
}
in your method on unchecked status of the checkbox you will have set the BackColor of the GrdiViewRow like this gvrow.BackColor= Color.Gray;
One important think is on the first load you will need to repeat similar logic of the GridView's OnRowDataBound so move it in method and reuse
protected void isActive_OnCheckedChanged(object sender, EventArgs e)
{
CheckBox chkStatus = (CheckBox)sender;
GridViewRow gvrow = (GridViewRow)chkStatus.NamingContainer;
//Get the ID which is the NetworkID of the employee
string username = gvrow.Cells[2].Text;
bool status = chkStatus.Checked;
if(!status)//this is checkbox is unchecked then set backcolor to Gray
{
gvrow .BackColor = Color.Gray;
}
