Asp.net - Checkbox Within A Datagrid, Findcontrol?
Nov 5, 2009I am limited to using ASP .NET 1.1, as for this environment I cannot upgrade to 2.0 or beyond Essentially, I have a very simple datagrid that has a checkbox in one of the columns, which is a template column...the code for the datagrid is this:
<asp:datagrid id="dgDates" OnItemCommand="gridEventHandler" BorderColor="Black" BorderWidth="1px"
CellPadding="3" runat="server" AutoGenerateColumns="False" HorizontalAlign="Left" AllowSorting="True"
OnSortCommand="SortData" OnItemDataBound="gridItemDataBound">
[code]....
Now, my issue is that when I set cbStaticRolling to the CheckBox control through FindControl on the e argument, it seems to set the variable okay, but doesn't seem to be setting the right one, or setting it properly, because "Checked" property is false regardless of whether I check the box or not?
Using FindControl To Target Literal
Jan 5, 2012I have a ListView called "orderReceiptTable" which I am able to properly access from the Code Behind. Within it is a literal called "orgName" which I obviously would like to populate with an organization's name. After much searching it was determined that FindControl was the right course of action. Perhaps I am using FindControl improperly but I am unable to actually have it "find" my Literal control. The code block is being called in the Page Load.
My code looks as such:
Dim orgNameString As String = getOrganizationName.getOrgName(organizationID).ToString()
Dim myOrgName As Literal = FindControl("orgName")
myOrgName = CType(orderReceiptTable.FindControl("orgName"), Literal)
If Not (myOrgName Is Nothing) Then

.net - FindControl Returning Wrong Control?
Sep 24, 2010I ran into a situation where FindControl was returning a control that wasn't a complete match of the Id I was searching by. There are two controls in the parentcontrol with similar Ids like: "MyControl" and "MyControlAlternate". When I call FindControl("MyControl") the control returned is "MyControlAlternate". I was wondering if anyone had any explaination why or thoughts as to what might be causing this problem. The way I got around this was implementing my own version of FindControl.

FindControl Cannot Find The Label Control?
Feb 14, 2012I have a DataList inside a DataList that causes my page to lose the controls. The page works and there are no errors, but my label is never found! This is odd because the label shows on the aspx page, it just doesn't remove the 2 items that I want it to remove. When debugging, it skips over the If statement altogether:
If lbl IsNot Nothing Then
If lbl.Text = "Self Directed" Or lbl.Text = "Systems" Then
lbl.Visible = False
[Code]....
This will only hide the text for "Systems", I have gone through each label in that particular question and each has hidden itself. This code does work on another page so I know that Self Directed is exactly how it is capitalized. I even copied and pasted from the database and it still wouldn't hide.

View 2 RepliesInsert Data Into Database With LoginView - FindControl Method?
Jun 4, 2009I have a web page where I want users to enter ratings for a particular software. I have got this working fine. What I am after now, is that users need to be logged in to enter ratings. I have dragged the loginview control onto the page and dragged all the other controls/datasources into this view. However now I am getting alot of squiggly lines regarding my controls not being declared. I have been told that I need to use the FindControl method. However I'm not sure on how to use it in my instance as I have a dropdownlist involved.
The controls are called: LoginView1, DropDownList1, TextBox1 and Button1 for the insert.
Any proper declarations so I can insert data into my database. Here is the code as it stands outside of the loginview:
Sub doInsert(ByVal Source
