My beloved problem is not being able to get hdnCompanyId element when GridView1_RowDataBound and drpCompanyList_SelectedIndexChangedfired.I am always getting null.(as showed at the commented line )
I have tried under GridView1_RowDataBound event method like e.Row.FindControl("hdnCompanyId")
but it did not work.
My final aim is to setting and getting this element to control selected items of my dropdownlist.
I think the code is well written but I guess I am missing something about hierarchy of the user control elements.
Can you help me about what I am missing?
I have found that the problem was choosing the wrong casting type of the input.It must be HtmlInputHidden rather than HiddenField.I hope someone can get useful info from that question.

Lina,
Although i don't have the answer for your problem I have however found a data consistency issue.
When your scrolling through the checkboxes you are overtyping the Label5.Text each time. Therefore the scrolling is pointless as Label5 will only ever show the value of the last Checkbox it found to have been ticked.
May i suggest the following alternative:
CheckBox x;
foreach (DataGridItem di in GridView1.Rows)
{
x = (CheckBox)di.FindControl("checkBox1");
if (x.Checked == true)
{
if(Label5.Text == "")
{Label5.Text = GridView1.SelectedRow.Cells[2].Text;}
else {Label5.Text = Label5.Text + " - " + GridView1.SelectedRow.Cells[2].Text;}
}
}
This will at least append the data onto the string seperating it with " - " if there are more the 1 Checkboxs selected. Feel free to change the separator as required.
I have a GridView with a button which sets all rows into edit mode (which is what I want). However I was wondering if there is a way to create a button that will update the whole gridview with my changes. Here is the code behind this.
<asp:GridView ID="gvUsers" runat="server" AutoGenerateColumns="False"
onrowcommand="gvUsers_RowDataBound">
<Columns>
<asp:TemplateField HeaderText="labelID" Visible="false">
<ItemTemplate>
<asp:Label ID="ID" runat="server" Text='<%# Eval("id") %>' />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="First Name">
<ItemTemplate>
<asp:Label ID="labelfirstname" Visible='<%# !(bool) IsInEditMode %>' runat="server" Text='<%# Eval("firstname") %>' />
<asp:TextBox ID="txtFirstName" Visible='<%# IsInEditMode %>' runat="server" Text='<%# Eval("firstname") %>' />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Last Name">
<ItemTemplate>
<asp:Label ID="labellastname" Visible='<%# !(bool) IsInEditMode %>' runat="server" Text='<%# Eval("lastname") %>' />
<asp:TextBox ID="txtLastName" Visible='<%# IsInEditMode %>' runat="server" Text='<%# Eval("lastname") %>' />

<asp:Button ID="Button1" runat="server" Text="Edit Mode" onclick="Button1_Click1" />
<asp:Button ID="Button2" runat="server" Text="View Mode" onclick="Button2_Click1" />
And here is the c#
private bool isEditMode = false;
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
BindData();
}
}
private void BindData()
{
string connectiongString = "Data Source=WSCJTCSQ1;Initial Catalog=LiquorStore;Integrated Security=True";
SqlConnection myConnection = new SqlConnection(connectiongString);
SqlDataAdapter ad = new SqlDataAdapter("SELECT id, firstname, lastname, nickname FROM Company", myConnection);
DataSet ds = new DataSet();
ad.Fill(ds);
gvUsers.DataSource = ds;
gvUsers.DataBind();
}
protected bool IsInEditMode
{
get { return this.isEditMode; }
set { this.isEditMode = value; }
}
protected void gvUsers_RowDataBound(object sender, GridViewCommandEventArgs e)
{
}
protected void Button1_Click1(object sender, EventArgs e)
{
isEditMode = true;
BindData();
}
protected void Button2_Click1(object sender, EventArgs e)
{
isEditMode = false;
BindData();
}
Thank you in advance!!
You can iterate thru you rows and get values in a textbox for specific row
foreach (GridViewRow row in gvUsers.Rows)
{
TextBox txtFirstName = row.FindControl("txtFirstName") as TextBox;
TextBox txtLastName = row.FindControl("txtLastName") as TextBox;
if (txtFirstName.Text!="" && txtLastName.Text!="")
{
// do what you need with values
}
}
So I'm using ADO.net Entity Data model in an ASP.Net (C#) Web page. I am dynamically adding and retrieving data to my database using gridviews. I am using master pages, and my gridview is in a contentplaceholder. My only issue with this code is that when my RowUpdating event fires, the gridview is null. I can call by BindGV function, and then the rest of the code updates the database perfectly fine, with the original data from the database I just bound to it, since the database was not updated yet. In all events, if I change bindGV() to Gridview1.databind(), the gridview is null. I think the datasource the gridview is referencing is becoming null at the end of the event when the data connection is closed, is there anyway to prevent this?

Not sure why the GridView is null, but instead of using a member variable i would use the sender of the event which is always the source of the event (in this case the GridView)
// ...
GridView grid = (GridView)sender;
Int32 id = Convert.ToInt32(((Label)grid.Rows[e.RowIndex].FindControl("lblId")).Text);
// ...

Thank Frank!
I belive you can get the DataBoundItem from the row which is a type of "PsaDataSet.PsaLinkRow" and use that you get the ProductId, Series, etc. and do the condition that you require. Also, you have and if condition inside an if condition with the same condition for both. You only need one.

In my row command event i write as follows code
protected void grdViewAttachment_Client_RowCommand(object sender, GridViewCommandEventArgs e)
{
SqlConnection m_Conn = new SqlConnection(Utilities.ConnectionString());
SqlCommand m_oCmd;
int iStID = int.Parse(e.CommandArgument.ToString());
int pk = 0;
int.TryParse(e.CommandArgument as string, out pk);
string strStoreProcName = null;
DataSet oDS1 = new DataSet();
if (e.CommandName == "Delete")
{
strStoreProcName = StoredProcNames.Attachments_uspDeleteAttachs;
m_oCmd = new SqlCommand(strStoreProcName, m_Conn);
m_oCmd.CommandType = CommandType.StoredProcedure;
m_oCmd.Parameters.Add("#AttachmentId", SqlDbType.Int).Value = Convert.ToInt32(e.CommandArgument.ToString());
m_Conn.Open();
m_oCmd.ExecuteNonQuery();
AttachmentDetails();
}
string fname = e.CommandName.ToString();
}
But i am not getting the value i am getting the exception as Input string was not in correct format can any one help me
es #Muhammad Akhtar was right .It should be like
int iStID = Convert.ToInt32(gridName.DataKeys[Convert.ToInt32(e.CommandArgument.ToString())].Value);
Specify Datakey property in your data grid . and you can access the data key value of the current row as above
add datakey name to your statement
ID_COLUMN should be a column from data table which you are binding to gridview
Write this code for row Created
protected void grdViewAttachment_Client_RowCreated(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
LinkButton lnkbtnAttachments=(LinkButton)e.Row.FindControl("lnkbtnAttachments");
lnkbtnAttachments.CommandArgument = e.Row.RowIndex.ToString();
// similarly write for other controls
}
}
Do not use Delete standard commandName otherwise you have to handle the "RowDeleting" event.
Take a look at this sample:
.aspx markup

As you are not passing command Argument this will always give null reference . Try this in your control where ever you required.
