Hi all,
I create a gridview dynamicly because I don't know the columns in advance.
I use the Templatefield to create a linkbutton.
Everything fine..I have the postbackurl and it works.
But now I need to do some extra stuff in the click event of the created
linkbutton.
I tried to assign a delegate to the linkbutton's click event but I never
gets in the procedure I assign.
How can I trap the click event?
Thank you.
Here is the code:
private void CreateGrid()
{
//Create the grid:
foreach (DataColumn col in dtt.Columns)
{
if (col.ColumnName .Equals("FakAID ") || col.ColumnName. Equals("markID" ) ||
col.ColumnName. Equals("FilID") )
continue;
if (col.ColumnName .Equals("Invoic e"))
{
TemplateField tempColumn = new TemplateField() ;
tempColumn.Head erText = col.ColumnName;
tempColumn.Item Template = new LinkButtonTempl ate(col.ColumnN ame,
"~/screen.aspx?nav =1&tab=I&cid=" , "markID");
grvSearchResult .Columns.Add(te mpColumn);
}
else if (col.ColumnName .Equals("File") )
{
TemplateField tempColumn = new TemplateField() ;
tempColumn.Head erText = col.ColumnName;
tempColumn.Item Template = new LinkButtonTempl ate(col.ColumnN ame,

Hi Milosz,
great thanks for the help I will try it.
One more thing the click event will be in the Template class.
How do I get it to be in the Page?
I want to use the LinkButtonTempl ate class in more pages and grids.
Thank you.

Hi Milosz,
WOW! great help thank you alot!
I understand what you mean with the user control way.
One more thing. This is on a search page and after clicking the search
button I know what to search for.
Then I create the grid.
But that's after the Page_Init and Page_Load.
Is there something I can do about that?
Thanks again.

Hi all,
I create a gridview dynamicly because I don't know the columns in
advance.
I use the Templatefield to create a linkbutton.
Everything fine..I have the postbackurl and it works.
But now I need to do some extra stuff in the click event of the
created
linkbutton.
I tried to assign a delegate to the linkbutton's click event but I
never
gets in the procedure I assign.
How can I trap the click event?
Thank you.

You have to recreate the grid because criteria have changed:

string criteria = txtCrieria.Text ;
// get data source based on carent criteria
