When to insert a dynamically created UC into a control

[Richard]

I have created a class that builds a custom grid object (StandardGrid).  In addition to that I have created a user control that I want to insert into the FilteringItem of the grid object.  When the user clicks on the button inside the user control I want to perform an action on the grid.  I'm not sure how to hook things up properly.  Here's what I currently have happening.  The GridFilterButton (user control) inserts fine into the grid initially but then isn't available on postback.  Any help would be appreciated.

 

 

 

void StandardGrid_ItemCreated(object sender, GridItemEventArgs e)

{

 

switch (e.Item.ItemType)

{

 

case

 

 

GridItemType.FilteringItem:

 

GridFilteringItem filteringItem = e.Item as GridFilteringItem;

try  

 

 

{

 

//Insert the GridFilterButton @ position 0 in the Grid

 

Control GridFilterButton = this.Page.LoadControl("~\\UserControls\\GridFilterButton.ascx");

filteringItem[

"CommandColumn"].Controls.AddAt(0, GridFilterButton);

Hi Richard,

Are you binding the Grid using AdvanceDataBinding techniques ? If not you need to manually bind the Grid after every postback.

Thanks

Hi guys,

You can specify CommandName value for the button which resides in the user control used for filtering and intercept the command when it is pressed taking advantage of the event bubbling mechanism of RadGrid. Note that the ItemCreated event will be raised on each submit as explained in this help topic.
