C# Gridview - Setting Up AutoGenerateEditButton
Mar 5, 2010
I'm having a problem getting the GridView.AutoGenerateEditButton property to do anything for me. Right now, I set it to true, and I don't even get the button added to my GridView, so obviously I can't even get any further to code the actual events. Here is what I have so far (sorry for the messy code; I'm getting close to my deadline and it's been a bit frantic):
[code]....
Now, the columns are being added exactly the way that I want, and the data is populating properly. However, I don't have the edit buttons that I assume I should have by setting the GridView.AutoGenerateEditButton property to true.

I have a databound gridview using datatable as datasource. Template fields are used to edit the row content.This cell value should get updated in the datatable on text_changed event without using gridView edit. Is it possible to overload the GridViewEditEventHandler for this purpose.

I'm using AutoGenerateEditButton and the Delete and Select ones as well.
I'd like to use images instead of text for the links.
How do I do this?
I don't want to manually create the command columns, since the AutoGenerate properties are used throughout a large project I'm working on.

The actual markup code is
[code]...
I'm not too sure whether setting the ShowEditButton property should be removed, but when I tried to do that I still couldn't set it programmatically.
Now in the code behind file I reduced the Page_Load method to this
protected void Page_Load( object sender, EventArgs e )
{
dvwSomeDetailsView.AutoGenerateEditButton = true;
}
What I want to achieve is that by changing the assignment in the Page_Load method I can hide / show the Edit button, but that does not work. When playing around in the markup file I can make the button show up or hide, but I can never change it from the code behind file.
I also tried to explicitly call dvwSomeDetailsView.DataBind after setting the property, but this also didn't work. Overriding OnPreRender and placing the code from the Page_Load method in their didn't do anything to improve this either.
Maybe I'm thinking too complicated - shouldn't there be an easy way to set programmatically whether the button should / shouldn't show?

when I click 'edit' I can edit rows in the the grid view but when I click 'update' nothing happens - I can still see the 'update' and 'cancel' buttons and it looks like the changes are kept but the database is not realy being updated. The Javascript is running but nothing happens. Doesn't even look the the 'RowUpdated' event is in effect.here is my code:
protected void GridView_RowUpdated(object sender, GridViewUpdatedEventArgs e)
{
if (e.Exception == null)

I have a panel control in gridview's template. I need to hide/unhide panel in javascript function, for that i need to pass panel's id to the javascript. The problem is that all panels have the same id in gridview, so I need to set unique id to each panel.
I tried to do:
<asp:Panel id= "Panel_<%# Eval("ID")%>" and some other variations but always get an error.
The panel contains some other controls, I need it to be server side because I need to set at code-behind (after checking if user is authenticated) What can I do? p.s. It doesn't have to be Panel, any other control that I can find with Findcontrol and can hold other controls.
Update:
I set the the js event in code behind:
protected void gvw_RowCreated(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
if (UserIsAuthenticated)
{
HyperLink title = e.Row.FindControl("lnkTitle") as HyperLink;
Panel panel = e.Row.FindControl("panel") as Panel;
title.Attributes.Add("onmouseover", "ShowHidePanel(" + panel.ClientID +")");
//All get the same id!!!
}
}
}

On the RowDataBound event of a gridview I am setting the name of the HtmlInputRadioButton inside the GridViewRow. The problem is that asp.net automatically makes the name unique therefore ungrouping the radio buttons.
Is there a way that I disable this?
Edit - Here's how I am setting the name:
[code]....
Due to the numbers "106" and "107" in the name of the respective radiobuttons it ungroups them.

I have develop a web application. I have put my web application in my server and user can access from any location.
My server regional and setting is English (US). Now my problem is
1) When user access to my system and his pc setting is English (UK), it will prompt and error
and after i debug i suspect it is because of Datetime conflict (dd/MM/yyyy and MM/dd/yyyy)
2) I cannot fix or limit my user to setting his/her pc regional setting to UK
So what can i do in my web application solve this issue?
(Can i write any code in my client side (.aspx) to convert or do standardization to US)

I need to perform some string manipulation to a columns contents in a GridView, and I'm using the DataBinding event for the template field for this. I'm converting all Environment.NewLine's to 's for outputting.
Here is the code:
[Code]....
It writes the correct, newly modified, string at the top - but why isn't it feeding back to the grid view?

what I am trying to do is add a method to my gridview's sorting event to add a class to the column being sorted so the user can know if the data is being sorted ascending or descending and on what column. I am currently trying to do it through a switch statement on the sort expression to determine what column it's coming from but I am unaware of how to set the css class.

I have a gridview, and I was trying to use SQLAdapter for the first time. I have it set up but I want the user to enter a Date in the last field of the Gridview and be able to update it. I was looking up examples, and I cannot get it to properly update. The field I want to be able to update is the "TADateUpdate" I have gotten it to show the texbox fields to edit, but I can't figure out a method to update properly.

I have a gridview with a bound column,a template field with an editable textbox and a template field with a readonly textbox.
The bound field value is coming from database. I will enter a value to the editable textbox field. I want to set a value to the third cell based on the entered value in second cell . If the second cell is lost focus i want to set the value to third cell . If the solution is with a javascript function i will be very happy.

I have a gridview that displays entries from a data table. I am giving users the ability to select a subset of the data in the table by having a textbox and search button in the grid view header. The search button fires the gridview row command, and changes the underlying sqlDataSource's select command, and adds the text value from the text box as a parameter.
Also, I have a "Show All" button in the header, that clears out the select parameters, so all entries in the table are shown. Again, this works perfectly.
What is NOT working is controlling the visibility of the "Show All" button control. Below is the html markup for the data grid header template:
<HeaderTemplate>
<asp:Button ID="btnShowAll" runat="server" CausesValidation="False" CommandName="ShowAll" Text="Show All" />
<asp:Button ID="btnSearch" runat="server" CausesValidation="True" CommandName="Search" Text="Search" ValidationGroup="vldSearch" /><br />
<asp:TextBox ID="txtSearchName" runat="server"></asp:TextBox>
<asp:RequiredFieldValidator ID="vldSearchName" runat="server" ErrorMessage="You have to provide an attorney name to search for." Text="*" ControlToValidate="txtSearchName" ValidationGroup="vldSearch" ForeColor="White"></asp:RequiredFieldValidator>
</HeaderTemplate>
In the Row Command event handler, here is how I am setting the visibility of the button:
If Not Me.dgAttorneys.HeaderRow Is Nothing Then
Dim btnShowAll As Button = Me.dgAttorneys.HeaderRow.FindControl("btnShowAll")
btnShowAll.Visible = Me.sqlAttorneys.SelectParameters.Count > 0
Trace.Write("Show all status is " & btnShowAll.Visible.ToString)
End If
The trace statement is showing the correct visible status - if the "show all" button is clicked, I do a SelectParameters.Clear() on the sqlAttorneys sqlDataSource.
Is my problem due to a misunderstanding of how the "FindControl" method works - I had assumed my new btnShowAll that I define is actually a reference to the "physical" control on the aspx page, so any changes I make to my local object is reflected in the control on the page.
If this is not the case, what is the best way to get a reference to the button control in the header row of the grid view?

I've been reading the posts here and I'm not finding, or maybe just not understanding, the answer I need so here's my problem.
I have a small gridview and the update works very well. The issue is I need to have one of the fields set to a value from my code either when the record is open for undating or when the update runs.
Here is my gridview and the datasource info:

Here's the RowUpdating event code:

Is tehre anyway to set the HeaderText dynamically on a gridview? I'm trying the below, it kind of works, but the problem is on the initial load nothing shows up, but when I postback then the new text populates:
grdvMyTest.HeaderRow.Cells[5].Text = GetTheCalculatedDate();
I've tried that in both Page_Load and grdMyTest_Load, but same thing happens in both. When the page initial loads the column header text is blank, when I click something causing a postback it pops up. I don't have a IsPostBack check around that line, so it should be running regradless. I'm guessing I'm doing it at the wrong event, either too eariler or too late.
