The 1st time I submit the form everything is working well, the second time theGridView1_RowCreated fires an exception when the property AssetClass is called. The error message isMust specify valid information for parsing in the string. This is becauserblAssetClass.SelectedValue is empty, but I don't uderstand why.

why the gridview RowDataBound event fires during a select command. I only expect it to run when the gridview is being populated with data. Is there some way to stop it from running when the select command is triggered?
View 3 RepliesI have a dropdownlist outside the gridview control. My griview control also have dropdownlist in the first column. I want to populate the dropdownlist inside the gridview control for all rows when the selected item is changed in the outside dropdownlist.
View 2 RepliesBasically, I have a gridview and it has RowEditing function, which to be fair has two lines of code
GridView1.EditIndex = e.NewEditIndex;
GridView1.DataBind();
When I press the edit button from one of the row in gridview, it hides the whole gridview!
To bring it back, I have to call the function which does the binding and suprisingly, it loads back in edit mode!
I have two gridview in a single webform, I need to fire one gridview RowDataBound event from another one gridview's RowCommand.

View 1 RepliesWhat is GridView Event "RowDataBound" ?
When it is used ? And How ?
I'm using a GridView to display some columns and rows that reside in a database. This works excellent. Because i wanted to add columns dynamically out of a List of names. Let's say we have a list with 5 names in it, then it dynamically creates a column for every name in the GridView.
Here's some code to display what i do:
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
//Create columns for each student
List<Student> allStudents = new Eetlijst.Business.Students().GetAll();
allStudents.Reverse();.......
How do i create the dynamic columns for each row? I create them with a DataBound event. So when the GridView databinds, the columns get filled with data. There is also a check inside to see if the row is in edit mode or not. So when i click on the edit button next to the row, the row goes perfectly in edit mode. The code i made adds a TextBox control to the cell.
When i fill in a value and press the Update button, it can't find any controls anymore and therefore i can't get the value i entered. The control is still there in the DataBound when i put a break point after it. But as soon as i click the Update button, all the controls of the cells are gone.
I searched on the internet and all i found is that it has something to do with the application firing a postback before it reaches the RowUpdating method.
So, how can i let the controls exist that i added to the cell when it is in edit mode?

Iam develoing web application using csharp on visual studio 2008. Now I have a problem. When I want to get a record or row on Gridview when I click on it Iam not getting. But on datagrid it is working.How can I achieve the same on Gridview. I want when I click on the Gridview Record a get a value put it in a session the use it on another page.The code Iam using is below.
[Code]....
I've following gridview:
<asp:Panel ID="pnlScroll" runat="server" ScrollBars="Auto">
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>

Now I am not able to understand why the OnRowCommand event is not firing. Nothing is happening on clicking the button in gridview.
protected void grdMain_RowDataBound(object sender, GridViewRowEventArgs e)
{
}
<asp:GridView ID="grdMain"
runat="server"
OnRowDataBound="grdMain_RowDataBound"
I have one button and gridview.
The button is located at the outside of gridview.
By clicking the button, I want to trigger the RowCommand event in that grid.
Obviously, I know that I can create same function to run it in that button to achieve samething in the RowCommand event.
However, I would like to know that techinically, I can simply trigger the RowCommand event from outside of GridView.
I have a gridview,sqldatasource and a link button for delete in the sample code below
When Delete is click the confirmation pops up. When I confirm yes, the rowdeleting event doesn't seem to be firing. I addeed a label to see if the event is firing. To avoid runtime errors I added a dummy but actual sql delete command. Once If I get it to work, I want call a stored procedure to delete the row.
My question is
1. Why is the gridview row deleting event not fired.
[Code]....
When a Gridview row is in edit, I need to default an empty textbox to today's date. I am close, but the defaulted date is is not saved to the database. I can key in the date and the date is displayed and saved to the database. Even more interesting:
1. The date is defaulted to - 5/17/2010
2. If I erase the month and key the "5" back in the data is not saved.
3. If I erase the month and then change the month to "6", the data is saved to the database. If any value is changed in the date the save works.

I have a very simple page that consisist of an UpdatePanel that contains a gridview. The gridview includes a delete button for each row, which should fire the Delete event. But the event never fires. If I set a breakpoint inside the event handler, it never gets hit and the row does not get deleted. When I say OK on the confirm dialog it just goes back to the page. I tried taking out the confirm button extender
