Forms Data Controls :: FindControl Failed To Work For GridView
Nov 8, 2010I have a gridview with several ItemTemplates. The first contains a checkbox the rest contain textboxes. I then added dynamically some bound controls like this:
BoundField bdfPrivName = new BoundField();
clsUtilities.SetBoundFieldCenter(ref bdfPrivName, "PrivName", "Priv Name");
BoundField bdfDescription = new BoundField();
clsUtilities.SetBoundFieldLeft(ref bdfDescription, "PrivDesc", "Description");
BoundField bdfLive = new BoundField();
clsUtilities.SetBoundFieldCenter(ref bdfLive, "Live","Active?");
grdExisting.Columns.Add(bdfPrivName);
grdExisting.Columns.Add(bdfDescription);
grdExisting.Columns.Add(bdfLive);
I then use FindControl to locate the checkbox and textboxes and perform my logic based the result
foreach (GridViewRow gvr in grdMissing.Rows) {
mckbAny = (CheckBox)gvr.FindControl("ckbAdd");
mtxtApplyDate = (TextBox)gvr.FindControl("txtAddApplyDate");
mtxtDateToAdd = (TextBox)gvr.FindControl("txtAddDateToAdd");
mtxtDateToRemove = (TextBox)gvr.FindControl("txtAddDateToRemove");
etc.
This all worked fine. I then got a request to put the bound fields as the second, third and fourth columns, after the check box and before the textboxes. I found that this was easy to do by changing the Add's to Inserts as follows:
grdExisting.Columns.Insert(1, bdfPrivName);
grdExisting.Columns.Insert(2, bdfDescription);
grdExisting.Columns.Insert(3, bdfLive);
It looked fine of the page, but the FindControls, all of them fail to work.

Forms Data Controls :: Create An Instance Of A TextBox In A GridView When Using FindControl?
Dec 28, 2010In my GridView I use FindControl/<FooterTemplate> with a TextBox that you can enter an integer with a comma
into the TextBox, because I create an instance of the Textbox first and then remove the comma out of the integer before the TextBox is used to update the table in the database.
However once the data is in the table and displayed in the GridView if you try to change the integer and use a comma in the GridView you cannot because FindControl/<EditItemTemplate> will not create an instance for you to remove the comma from the integer before it updates the table because FindControl/<EditItemTemplate> doesn't allow you to create an instance of the TextBox first, instead when you try to use the instance that looks like was created it gives an error stating:
Object reference not set to an instance of an object.
So the question is:
HOw do you create an instance of a TextBox in a GridView when using FindControl/<EditItemTemplate>?
<form id="form1" runat="server">
<div>
