Forms Data Controls :: Cannot Identify Controls Within Repeater / Object Reference Not Set To An Instance Of An Object

Nov 23, 2010

I have created an ASP page to display records for auditor review and response. The page consists of two repeaters that display 5 rows from a database at a time. for each row displayed, a RadioButtonList, containing two buttons is attached. If the second button is selected, an input text box is displayed to allow auditor comments.

My situation is that I cannot find a way to identify which row is being selected? When I select the Button that should enable the text box, I'm receiving the following error:

"Object reference not set to an instance of an object"

I'm just starting out in ASP coding and would like to know what I'm not doing right?

Data Controls :: Select Item DropDownList In GridView - Object Reference Not Set To Instance Of Object

Aug 30, 2013

I have a dropdownlist attached to a cell when edit is selected.  I am using the following code to populate the drop down list with the value that is on the row.

dlBU.Items.FindByValue((e.Row.FindControl("lblBU") as Label).Text).Selected = true;

This works famously when I have a value in the cell.  It fails when the cell has not yet been populated.  Is there an if then clause that if the value of e.Row.findcontrol("lblBU") is null no default value?

Data Controls :: Object Reference Not Set To Instance Error

Aug 18, 2015

I have the following code on RowDataBound my gridview:

If (e.Row.RowType = DataControlRowType.DataRow) Then
e.Row.Attributes.Add("onkeydown", "javascript:ChangeRowColor('" & e.Row.ClientID & "')")
e.Row.Attributes.Add("onkeyup", "javascript:ChangeRowColor('" & e.Row.ClientID & "')")
e.Row.Attributes.Add("onclick", "javascript:ChangeRowColor('" & e.Row.ClientID & "')")
Dim lbl As Label = CType(e.Row.FindControl("BOD_NPRGSTA"), Label)
lbl.Attributes("onclick") = Page.ClientScript.GetPostBackClientHyperlink(GridView1, "Select$" & e.Row.RowIndex)
End If

I would use it to intercept the click on the row of GridView when I click on the Label lbl.The problem I have because when I click on the same label me "smashing" the gridview itself. (He added a blank row for no reason).
