C# - GridView EditItemTemplate Not Showing On First Click?
Jan 5, 2010
I have a GridView with an EditItemTemplate, to which I am binding a Dictionary
<asp:GridView runat="server" ID="VariableList" ShowHeader="false" AutoGenerateColumns="false" OnRowEditing="VariableList_RowEditing">
<Columns>
<asp:BoundField ReadOnly="true" DataField="Key" />
<asp:TemplateField ItemStyle-Width="300">
[Code].....
If I set a breakpoint on the grid.EditIndex = e.NewEditIndex; line, it is setting the value to 0 which is the first item which is correct.
However, the asp:TextBox is not displaying. It is showing what is in the ItemTemplate and not in the EditItemTemplate.
However, if I click on Edit button again, it then displays the TextBox.

I have a Gridview that works and in one of the TemplateFeld EditItemField I have a checkboxlist that I dynamically create based on the row ID. My first and third row work as expected, when I click on the 'Edit' link the Job Posting column shows up with checkboxlist. The second row does not do this.
I think it's something with gvRecruiters_RowDataBound but I can't see it.
default.aspx
HTML Code:
<asp:GridView ID="gvRecruiters" runat="server" AutoGenerateColumns="false"
OnPageIndexChanging="gvRecruiters_PageIndexChanging"
OnRowCancelingEdit="gvRecruiters_RowCancelingEdit"
OnRowDataBound="gvRecruiters_RowDataBound"
OnRowDeleting="gvRecruiters_RowDeleting"

I have put my gridView inside an UpdatePanel with Timer control for auto refresh.The gridView has a linkButton column which is bounded to referenceNo column from database.
On click of this link button i want a panel to get visible. This Panel contains details corresponding to the referenceNo shown in differnt controls (mostly texboxes). Do i necessarily need to put the panel inside the Update Panel.If not how do i do it?
I have tried putting panel outside UpdatePanel, but it doesn't show panel on clicking the linkbutton nor does the values are updated inside this panel (if panel's visibility is set to true by default for testing purpose).

I have a gridview and it has two EditItemTemplates. I want to update the items inside the second dropdown (EditItemTemplate) when I select an item from the first dropdownlistbox (EditItemTemplate). I want to update dropdownlist2 when I select an item from dropdownlist1. How can I do this?

I have a template field within a GridView to display a checkbox in edit view and some custom text in normal view.
The results of the query to populate the grid are coming back in a DataSet.
In the edit view I can't get the checkbox to accept the column that is retuning from the DataSet (which is in T/F format) as it says its not the correct type. Even if I return "true" or 1 in the column it still dosn't work.
I take it I need to convert but can't get the syntax correct in this context
<EditItemTemplate>
<asp:CheckBox ID="cbPostToFarm" runat="server" Checked='<% Bind("BOOL_COL")' />
</EditItemTemplate>

In my Gridview when a user edits a row, I'm showing couple of asp:TextBox boxes using the EditItemTemplate.
One of the Text Box is bound to the UpdateParameters of my asp:ObjectDataSource. However the Second Box is not bound to any of the update parameters. I'm assigning a custom value to the second box.
Now my problem is, when the row is updated how do i read the value of my second text box??
I tried catching the value of the second text box in Grid_RowUpdating and ObjectDataSource1_Updating but I'm unable to find the second control.

I am using eWorld.UI.CalendarPopup in my GridView.EditItemTemplate. My GridView is nested by UpdatePanel. At GridView_ItemCreated, I auto add initial row at GridView Footer. I faced problem that, CalendarPopup is working when I add 1st row. Once I click "Add" link and GridView refreshed by AJAX, CalendarPopup no longer working. I can't click or even change its date value. I have tried to download latest 2.0.9, include eWorld.UI.Compatibility assembly; changed controls to point use "ewc" instead of "ew". and few other ways found from Google. However, still no luck.

I have a GridView control on a page with a Panel that has a DefaultButton. I am trying to get the "Update" button to work with the Enter key when a user edits a row. It works fine with the mouse. When I click on "Update", the row reverts back to View mode and the updated value is shown.
When the GridView is in the Panel, the Panel's default button (which submits the page) fires when I press Enter, before the RowCommand is even handled, and the update is lost.
When the GridView is not in the Panel, some other seemingly random button in the Panel fires, but not the "Update" button in my row's EditItemTemplate. Specifically, there is a CalendarExtender on the page, and the extender's popup button fires. Totally not what I want.
How can I get this to behave correctly?
Here is the structure of my mark-up code:
<asp:Panel ID="Panel1" runat="server" DefaultButton="btnSubmit">
<!--Form with controls-->
<asp:ImageButton ID="btnWSPODateCal" runat="server" />
<!--this button fires when I press enter while editing a grid row:-->
<ajaxToolkit:CalendarExtender ID="CalendarExtender1" runat="server"
TargetControlID="tbPODate" PopupButtonID="btnWSPODateCal" />
<!--more controls-->
<div class="button_row">
<asp:ImageButton ID="btnCancel" runat="server" />
<asp:ImageButton ID="btnSubmit" OnClick="btnSubmit_Click" />
</div>
</asp:Panel>
<asp:GridView runat="server">
<Columns>
<asp:TemplateField>
<EditItemTemplate>
<asp:ImageButton CommandName="MyUpdate"
ID="btnSubmitRow" runat="server"
CommandArgument="<%# ((GridViewRow) Container).DataItemIndex %>" />

I have requirement to bind ASP.Net DropDownList control in EditItemTemplate of GridView.
I preferred the tutorial:
[URL]...
i have followed same steps just but difference is i have a edit imagebutton with commandname="Edit".Also dropdown needs to be binded from different table(directory) and not the table through whicch grid is binded(details).
if (e.Row.RowType == DataControlRowType.DataRow && (e.Row.RowState & DataControlRowState.Edit) == DataControlRowState.Edit && GridView1.EditIndex == e.Row.RowIndex)
{
DropDownList DStatusEdit = (DropDownList)e.Row.FindControl("DStatusEdit");
string query = "select distinct status from directory";
SqlCommand cmd = new SqlCommand(query);
DStatusEdit.DataSource = GetData(cmd);
[CODE]..
the page is running but when i click edit image button the dropdwn shows but no data in dropdown binded it is empty.
My gridview is inside update panel.
How can i achieve this?
Should dropdownlist in my case be binded inside rowcommand and how?
