I use this Bulk Edit GridView Control http://aspnetrealworldcontr.codeplex.com/
I use Linq and have a Stored Procedure to update the database.
I don't Understand how to use the Save Button to update the database.
You are suppose to update all the rows with one button.
In the example they use SqlDataSource
example
<div>
<asp:Button runat="server" ID="SaveButton" Text="Save Data" />
<rwg:BulkEditGridView ID="EditableGrid" DataSourceID="PubsDataSource" AutoGenerateColumns="False"
DataKeyNames="au_id" SaveButtonID="SaveButton" runat="server">
<Columns>
<asp:BoundField HeaderText="Last Name" DataField="au_lname" />
<asp:BoundField HeaderText="First Name" DataField="au_fname" />
<asp:BoundField HeaderText="Phone" DataField="phone" />
<asp:BoundField HeaderText="Address" DataField="address" />
<asp:BoundField HeaderText="City" DataField="city" />
<asp:BoundField HeaderText="State" DataField="state" />
<asp:BoundField HeaderText="Zip Code" DataField="zip" />
<asp:CheckBoxField HeaderText="Contract" DataField="contract" />
</Columns>
</rwg:BulkEditGridView>
<asp:SqlDataSource ID="PubsDataSource" runat="server"
SelectCommand="SELECT [au_id], [au_lname], [au_fname], [phone], [address], [city], [state], [zip], [contract] FROM [authors]"
UpdateCommand="UPDATE [authors] SET [au_lname] = #au_lname, [au_fname] = #au_fname, [phone] = #phone, [address] = #address, [city] = #city, [state] = #state, [zip] = #zip, [contract]=#contract WHERE [au_id] = #au_id"
ConnectionString="<%$ ConnectionStrings:Pubs %>" />
</div>
My Code - Only the Quantity can be updated.

I would like to make a column editable in a gridview but without the edit column (the one with the keys update, cancel ...) due to space problems. I tried to recall the javascript functions related to those buttons in the onRowDataBound but onclick event is not taken. Here my code. Can anyone help me please?
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
if (e.Row.RowIndex == GridView1.EditIndex) //GridView is in edit mode
{
//update or cancel buttons
LinkButton updateBtn = (LinkButton)e.Row.Cells[0].Controls[0];
string updateScript = ClientScript.GetPostBackClientHyperlink(updateBtn, "");
Button1.Attributes["onclick"] = updateScript;
string cancelScript = string.Format("javascript:__doPostBack('{0}','Cancel${1}')", GridView1.ID, e.Row.RowIndex);
Button2.Attributes["onclick"] = cancelScript;
}
else //GridView is in read mode
{
//edit button
string editScript = string.Format("javascript:__doPostBack('{0}','Edit${1}')", GridView1.ID, e.Row.RowIndex);
e.Row.Attributes["onclick"] = editScript;
}

I've done my research here and I can now succesfully get a value of a hidden boundfield column in my gridview. The problem is I can't target the a hidden column of the row that I selected.
can I use GridView1.SelectedRow.Cells[7].Text; something like that on a hidden column.Is it possible?
here is my code:
protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
//GridView1.Columns[7].Visible = true;
//stock_id_gridview_1();
foreach (GridViewRow row in GridView1.Rows)
{
string id = GridView1.DataKeys[row.RowIndex]["id"].ToString();
con.Open();
cmd = new SqlCommand(#"SELECT transaction_id,transaction_number
FROM stocks_history
WHERE id = #id", con);
cmd.Parameters.AddWithValue("#id", id);
rdr = cmd.ExecuteReader();
if (rdr.HasRows)
{
while (rdr.Read())
{
transaction_id = rdr["transaction_id"].ToString();
//lbl_test_id.Text = rdr["transaction_id"].ToString();
transaction_number = rdr["transaction_number"].ToString();
lbl_test_id.Text = transaction_id + " " + transaction_number;
}
}
con.Close();
}
here is my gridview:
<asp:GridView ID="GridView1"
CssClass="table table-hover table-striped"
runat="server"
AutoGenerateColumns="False" DataKeyNames="id" OnSelectedIndexChanged="GridView1_SelectedIndexChanged">
<Columns>

<ControlStyle CssClass="btn btn-info btn-sm"></ControlStyle>
<ItemStyle Width="150px"></ItemStyle>
</asp:ButtonField>
</Columns>
</asp:GridView>
I wanted to target this bound field:
<asp:BoundField DataField="id" Visible="false" HeaderText="id"
SortExpression="DateField" />
If You use attribute DataKeyNames, you can take value from invisible column like
Use Attribute
<asp:GridView runat="server" ID="GridView" DataKeyNames="id">
</asp:GridView>
And you can access the data
var id = GridView.DataKeys[RowIndex].Values[KeyIndex]
To get selected row hidden column value
var id = GridView.DataKeys[GridView.SelectedRow.RowIndex].Values[0];
I am developing an ASP.NET intranet web application which is a Quiz Engine. Since I am a new ASP.NET developer, I have a table that shows some feedback received from the users and the admin has the ability to accept or reject these feedback using the DropDownList.
Under this table, there is a JQuery Accordion that when the Admin clicks on it, he will see a table with the received feedback for the last three months. But when the admin accepts or rejects one of the feedback and then clicks on the Accordion, he will see the that table but without that feedback even if the feedback is one of the feedbacks submitted last month. However, when you refresh the page and then clicks on the Accordion, he will see it.
So is there any functionality that will help me to get an auto-refresh table with refreshing the whole page?
Any help please?

In the trigger you mentioned Click event, but in the code behind you have only DropDownList_SelectedIndexChanged event.
Instead you can trigger the SelectedIndexChanged event for the DropDownList as
<asp:AsyncPostBackTrigger ControlID="DropDownList" EventName="SelectedIndexChanged" />
You just need to trigger a valid event in the code behind.
Update: Since the SelectedIndexChanged updates the database, so you need to refresh the DataGrid to populate the updated data.
Add this line code at the end of SelectedIndexChanged method:
GridView2.DataBind();
use ajax update panel this may help http://ajax.net-tutorials.com/controls/updatepanel-control/
I am developing an intranet web application which works as a Suggstions Box. The Admin will see a list of all submitted suggestions in a GridView and he has the ability to accept or reject these suggestions through the DropDownList that is added to the GridView. Besides that, there is a DropDownList at the top of this GridView to filter the suggestions based on the Division of the user who submitted one of these suggestions.
In addition, under this GridView, there is another GridView that shows the suggestions with their status as Accepted or Rejected. This GridView will be refreshed immediately after each time the admin accepts or rejects one of the suggestions. Also, the Admin has the ability to print this GridView.
Everything was working fine before adding the second GridView inside the UpdatePanel control, but now the filter for filtering the suggestions in the first GridView is not working. Any idea? Any help please?

Can you specify what is the id for the 1st grid?
What I can conceive is that maybe you are not updating the updatepanel manually on your selectedIndex change event
using (SqlConnection conn = new SqlConnection(connString))
{
using (SqlCommand cmd = new SqlCommand(updateCommand, conn))
{
cmd.Parameters.Clear();
cmd.Parameters.AddWithValue("#StatusID", suggestionStatus);
cmd.Parameters.AddWithValue("#ID", ID);
conn.Open();
cmd.ExecuteNonQuery();
}
conn.Close();
}
GridView2.DataBind();
UpdatePanel1.Update();
Also in your aspx set UpdateMode="Conditional"
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
Code:
<asp:GridView ID="gv_Recruit" AutoGenerateColumns="False" Width="100%"
runat="server" OnRowCreated="gvStates_RowCreated"
OnRowDataBound="gvStates_RowCreated">
<Columns>
<asp:BoundField HeaderText="key" DataField="key" />
<asp:BoundField HeaderText="Name" DataField="Name" />
<asp:BoundField HeaderText="Quota" DataField="Quota" />
<asp:BoundField HeaderText="Session" DataField="Sess" >
<ItemStyle HorizontalAlign="Center" />
</asp:BoundField>
<asp:TemplateField HeaderText="">
<ItemTemplate>
<asp:DropDownList ID="ddlCities" Width="100%" AutoPostBack="true" runat="server" OnSelectedIndexChanged="ddl_selected">

</asp:TemplateField>
<asp:BoundField HeaderText="Recruiter" DataField="Recruiter" />
<asp:BoundField HeaderText="MN Phone" DataField="MN Phone" />
<asp:BoundField HeaderText="Cell Phone" DataField="Cell Phone" />
</Columns>
</asp:GridView>
Code Behind:
protected void ddl_selected(object sender, EventArgs e)
{
string _dd_value = ((DropDownList)sender).SelectedValue;
string trying_to_get = gv_Recruit.Rows[???].Cells[0].Text.ToString();
string also_tried = gv_Recruit.SelectedRow.Cells[0].Text.ToString();
}
Basically what I'm trying to do is get the key value from the first row when the drop down is changed so I can perform an update ???
Can't figure this out.
Thanks in advance for the help...
Try
GridViewRow gRow = (GridViewRow)(sender as Control).Parent.Parent;
string trying_to_get = string.Empty;
if (gRow != null)
{
trying_to_get = gRow.Cells[0].Text;
}
