I am trying to make certain elements of template columns not visible when in edit mode. I am trying to access these elements in the prerender handler for the grid. They are always coming up null. In particular, the sourceLookUpButton which I want to make not visible is null. Here is the code. I appreciate any help. Thanks
| protected void providersGrid_preRender(object sender, EventArgs e) |
| { |
| foreach (GridDataItem item in providersGrid.Items ) |
| { |
| if (item.OwnerTableView.Name == "FeedTableView" && item is GridEditableItem) |
| { |
| GridEditableItem editableItem = item as GridEditableItem; |
| try |
| { |
| ImageButton lookup = (ImageButton)editableItem["feedName"].FindControl("sourceLookUpButton"); |
| lookup.Visible = false; |
| RadGrid package_grid = (RadGrid)editableItem["packageGrid"].FindControl("packageGrid"); |
| package_grid.Visible = true; |
| } |
| catch (Exception e1) |
| { |
| int x = 1; |
| } |
| } |
| } |
| } |

Thanks as always Shinu. I actually had to use GridEditFormItem rather than GridEditableItem and then it worked. I was able to implement it in the itemdatabound event handler. Here is my code:
| if (e.Item.OwnerTableView.Name == "FeedTableView") |
| { |
| if (e.Item is GridEditFormItem) |
| { |
| GridEditFormItem editItem = e.Item as GridEditFormItem; |
| try |
| { |
| ImageButton lookup = (ImageButton)editItem["feedName"].FindControl("sourceLookUpButton"); |
| lookup.Visible = false; |
| RadGrid package_grid = (RadGrid)editItem["packageGrid"].FindControl("packageGrid"); |
| package_grid.Visible = true; |
| } |
| catch (Exception e1) |
| { |
| int x = 1; |
| } |
| } |
| } |
