Forms Data Controls :: CS0117, Not Finding _DataBinding Event?
May 25, 2010
I know there are lots of intelligent people out here, so I am looking for a little help here.I'm getting an error on compile-time going onto an ASP.NET 2.0 site hosted on IIS 6 in Windows Server 2003. I get the following error:"CS0117: 'ASP.sku_maintenance_aspx' does not contain a definition for 'GridView1_DataBinding'"My ASP.NET Source Code is Here:
[Code]....
I've looked at the @Page attributes, tried recreating the code from scratch, and yet nothing works. I'm seeing this issue in similar pages, but I feel if I figure it out for one, it'll work for all of them.

Im having trouble accessing controls inside the gridview. I have a formview control on a aspx page and inside this formview i have controls that are bound to a datasource. Which works hundred percent. Also inside this formview i have a gridview which i have created my own template. Gridview1 has 3 columns with textboxes in each column.
Column 1 - LogDate
Column 2 - LogBy
Column 3 - Number dialed
Now this is what im trying to do. I have a dial button inside formview1 along with 4 textboxes which has telephone numbers in it. When i click on the dial button i want the time to be populated into Textbox1 which is inside gridview1 and at the same time Textbox2 to be pupulated with the Username as well as the number must be populated into Textbox3 inside gridview1.

I have a listview control which is bound to DataTable object. When a user clicks "Add", I am creating a new row in the underlying datasource and refreshing the datatable so that it includes the new row and displaying the listview. My requirement is to "select" the newly added row after listview is refreshed. I have the ID of the newly created row and it is bound as one of the columns in the datatable.Now my question is, how can I get the index of that particular row which was newly created from the Listview so that I can set its SelectedIndex.

I have a datagrid setup where I have a column of checkboxes setup, several informational columns for the user, and a hidden ID column. I have set up the loop to check with checkboxes have been checked, but I am having troubles finding the ID of the row that has been checked. The following code results in a "Object reference not set to an instance of an object" error:
For Each row As GridViewRow In GridView1.Rows
Dim cb As CheckBox = row.FindControl("ParticipantSelector")
If cb IsNot Nothing AndAlso cb.Checked Then
Dim productID As Integer
productID = CType(row.FindControl("ID"), Label).Text
Response.Write("You have selected " & productID & "<br>")
End If
Next
I am sure that I don't have something right here.

I am facing one strange problem,I have a gridview in which the last two columns have checkboxes and on those checkboxes click event I am doing some database operations.I also have one checkbox that is outside the gridview which actually shows or hides some of the gidview columns.This was all working well but now I have shifted that grid to a user control because I have to use it in two pages.The problem now is,When the page first loads and I click the check box or any control in the page that is outside the grid then it works perfectly.But once I click any of the check box within grid view column then its behavior chages, now even if I click the checkbox that is outside the grid then also the checkbox_CheckedChanged event of the checkbox that is whithin gridview is fired.That checkbox event then behaves something like a page_load event that is called for every page load and for every event with in the page after it is called once.
