Forms Data Controls :: Access A Control Inside A Repeater Control And Change Its Properties?
Nov 26, 2010
I need to access a control inside a repeater and change its properties. To enable it or not. I got an erorr message Object reference not set to an instance of an object. Here is my code inside a method. protected void
rptCAP_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
LinkButton lnDel = (LinkButton)rptCap.FindControl("lnkDelete");
lnkDel.Enabled = false; //<<<<< this is where the error occur
}
When I place the repeater inside a user control INSIDE ANOTHER user control and onto the page this works - the property is correctly set, if I inspect it inside the EnsureChildControls() method of the custom control the composite control's Value propertyis set to Eval("value") as intended.
I am using a repeater control and i want to use one more repeater control inside the existing repeater control .
Like this:
<asp:Repeater ID="Repeater1" runat="server"> <HeaderTemplate> </HeaderTemplate> <ItemTemplate> <!-- start child repeater --> Here I want to use one repater control <!-- end child repeater --> </ItemTemplate> </asp:Repeater>

i have a repeater that displays data from a SQL Server Database. I also want to display an int from the database for the specific item and allow the user to add 1 to the value of that int by clicking a button (almost like a pole). It would work similiar to a 'like' button on Facebook.e.g.
Basically as the title of this thread states, I have a FormView that has a GridView inside it and my ObjectDataSource that populates this grid cannot access the Grid.
The Control Id needs to be the name of the Grid I want to access, however through the 'wizard' the Control parameter drop down cannot 'see' the grid I need, only the FormView that is in.
I have tried numerous ways to get round this and am struggling now..
I've tried the following...
ControlID="FormView.GridView1"
ControlID="FormView.FindControl("GridView1")
ControlID="<%= GetNameOfGrid %>"
and numerous other attempts that also failed that I now cant remember...

how I access /retrieve values of checkboxlist inside a repeater? My code is below..is it the same as if it was not inside a repeater? My other concern is how do I distinguish these checkboxes because basically what 's going to happen here is based on which checkbox is selected I need to query an xml file to get the location of a folder which I'm then going to zip up and allow user to download..So here's the breakdown. I have an accordion panel using jquery ui. Each panel hold a product and each product has the same checkboxes..so depending on which product the user wants to download files for which he/she will indicate by opening the accordion panel for that product and checking which checkboxes/file they want to download . So how will I know which product the user clicked the checkboxes for being that I'm using this repeater which just one ID?
[Code]....
can I still use this code or will it not work cause it's inside a repeater..also I was going to use jquery to add an onclick event to the checkbox so how can I do that now with me using this control?
[Code]....
Here's another issue..I can't even assign values to the checkboxlist using databinding..so how am I suppose to do this.. Server Error in '/ArchitectView' Application.
