When I edit and update a normal gridview row using a stored procedure the griddview passes all the correct peramaters to my stored procedure.
Now Iv'e changed one of the columns to be a dropdown list while in edit mode. And it now says that the parameter associated with that column is missing?
What do i need to change to get it to pick the value out of the drop down list and pass it to the parameter.
Cheers.

Do you use the GridView control with any datasource control? Do you use the Bind method with the DropDownList? You can define the ControlParameter or ganeral Parameter in the datasource control to get the value from the DropDownList.

Standard question #2:
What error message do you get?
You have a smiley in the code where there should only be a parenthesis. I guess that it's the characters ; ) that causes that smiley, which means that you have a semicolon in the middle of the statement. As semicolons separate statements, you have split your statement in two, which will each cause a syntax error.

Add the attribute in the following way
private void Repeater1_ItemDataBound(object sender, System.Web.UI.WebControls.RepeaterItemEventArgs e)
{
if(e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
HtmlInputText txt = (HtmlInputText)e.Item.FindControl("txtOnNBH");
txt.Attributes.Add("onchange","fun('" + Repeater1.ClientID + "')");
}
}

Initialize data set before filling it ... like ..
DataSet1 = New DataSet
OleDbDataAdapter1.Fill(DataSet1, "Attendance_Details")
also remove DBReader.Close() .. because you have not used it at alll...

Hi,
I have a problem with a datagrid.
I want to add an extra row to it, this works fine by building tablecells and add them to the grid for each entry in the grid.
The extra rows can be edited by the user, but I don't know how I can bind this extra rows to my datagrid, so the changes of the user are recognized by the webform.
can you please help me with my Problem, or is it impossible to add extra rows, that can be edited by a user?
thank you for your help

Hi,
I am using ASP.NET 2.0 with VB.NET. I want to hide some column if user is not logged in.
So how to hide any column in repeater control dynamically - I m bit new to .net 2.0 and using repeater control first time.
Thanks.

+Use the data binding expression to set the Visible property of the element that you want to hide.
+Use the ItemCreated/ItemDataBound event of the Repeater control to hide the control if the user is anonymous.

+ Specify a ControlParameter in the datasource control that you use with the FormView, and you can point the parameter to the FileUpload control.
+ You can simply use a general Parameter and get reference to the FileUpload control in the FormView using the FindControl method to the read the file path.

Place all your server controls inside a form with runat="server" attribute. For example,
< asp:TextBox id="TextBox1" runat="server"/>
< asp:TextBox id="TextBox2" runat="server"/>
< asp:TextBox id="TextBox3" runat="server"/>
