I have a GridView with a TemplateField where I'm hosting a button. The button has an event hanlder OnClick, so when it is clicked it will execute some code.The problem I'm having is that when I click the button in a row, the Button event handler is not excecuted right away. Instead, the GridView selectedIndexChanged is fired and then I need to click my button again to fire the button's event handler.So, is there a way I could know if the button or the row was clicked in the GridView SelectedIdexChanged event? And why the Button's event handler is not firering right away?

I have a GridView that binding on Page_Load, and that is not the intent. Ideally, the GridView only loads on PostBack.

The bindClientDropDownList, by the way, does not call SearchResultsGridView.DataBind() on its own, so that can be ruled out.
I am new to asp.net (I may use some incorrect termology while I explain my issue...) and need some help with DropDownList in Gridview. Currently I have a GridView set up with three Columns bound to a database: Column1 - some kinda of index, Column2 - string, Column3 - DropDownList(called Active). So far when I build the page, all the columns show up and the DropDownList appears and the values are bound correctly. I want to change a value in the DropDownList and automatically update that value in my database.
I have set AutoPostBack = true and I made a DataObject (called UpdateActive) to update the database (it takes 2 inputs, the Column1 index and Column3 DropDownList value).However, I don't know how to find the row that I am changing, is there a way to figure out what row it is (like finding the Column 1 index?). Also, I don't want to have to click a button to update the data.

how can i populate the detailview in insert mode with values from gridview on selection?

I have a GridView, with a DropDownList as one of the Columns. I can get the SelectedIndexChanged method to trigger - but I cannot figure out how to get other Data regarding which row this triggered on i.e. if I could get the value in the ID column (DocID below), that would be great. My code is a bit too long, so I am just posting snippets. In the *.aspx file I have:
[Code]....
In the *.aspx.cs File:
[Code]....
I am wondering if I can get the DocID from within StatusDropDownList_SelectedIndexChanged - so that I can make appropriate changes to the Database. For e.g. in the RowDataBound event, which I had a GridViewRowEventArgs e, I could easily do e.Row.DataItem - to get the DataItem, I am wondering if I get/do something similar in the SelectedIndexChanged method. (I would prefer this be not the GridView Row Index i.e. I would prefer the DataItem if possible.)

View 6 RepliesI have a checkbox placed inside a gridview:
<GridView><asp:TemplateField HeaderText="Driver"> <ItemTemplate> <asp:CheckBox ID="CheckBoxDriver" AutoPostBack="true" OnCheckedChanged="GridView_Persons_SelectedIndexChanged" ValidationGroup='<%# Eval("ID") + "-" +((GridViewRow)Container).RowIndex %>' CssClass="CXDriver" runat="server" Checked='false' /> </ItemTemplate> </GridView>
For example: A listViewItem 1 has 3 drivers are checked, A listViewItem 2 has 2 drivers are checked.
Therefore, if changing the selectedIndex of the list, the checkbox indexChanged event will be fired.
How could I disable the autopostback of the checkbox during the listview item changed.
I have a grid with edit link.
when user clicks onedit link , i want to show modal popup extender which displays text boxes for editing those data.
when user finishes editing the grid should again updated.
I have a set of 4 buttons which part of a gridview template and I load the gridview on page_load. The datasource for the gridview comes via my controller as I am using Microsoft's Model View Controller design pattern. I set 4 public properties for each of the 4 buttons, which I can access in my controller class/method. However, when I call the method for the gridview, which sets the datasource for it on page_load, I get an error message when I try to set the enable to false. It says "Object not set to instance of object". The objective I am trying to do here is a check on a returned value, which I can achieve, and based on the return of the value that is returned, to either set the button enable to true or to false.
Unfortunately, I am getting this Object not set to instance of object error message, and I do not know how to resolve it.

I want to call a SUB for each line of a gridview.
I'm trying similar to how I did call a FUNCTION in a Formview with
[Code]....
The page returnes a BC30518: Overload resolution failed because no accessible 'ToString' can be called with these arguments
and marks this below it: target.SetDataBoundString(5, System.Convert.ToString(buchungsbutton(eval("terminid")), System.Globalization.CultureInfo.CurrentCulture))
So I have a GridView and several events that can be triggered (such as filtering and inserting a new record) to manipulate the GridView. I want to make sure that I'm not calling DataBind on Page_Load, especially since I might have to call it again when certain events fire. Is there a way I can make it so I only have to call DataBind once on the GridView after Page_Load and anything else has fired? Like some event that will absolutely fire last where I can put my DataBind?
The reason I need to do this is because the DataSource for the GridView is set programmatically from a DataView when the page is loaded, so DataBind needs to run every time. Just, hopefully, not multiple times each time...
