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("Invoice"))
{
TemplateField tempColumn = new TemplateField();
tempColumn.HeaderText = col.ColumnName;
tempColumn.ItemTemplate = new LinkButtonTemplate(col.ColumnName,
"~/screen.aspx?nav=1&tab=I&cid=", "markID");
grvSearchResult.Columns.Add(tempColumn);
}
else if (col.ColumnName.Equals("File"))
{
TemplateField tempColumn = new TemplateField();
tempColumn.HeaderText = col.ColumnName;
tempColumn.ItemTemplate = new LinkButtonTemplate(col.ColumnName,
"~/screen.aspx?nav=1&fid=", "FilID");
grvSearchResult.Columns.Add(tempColumn);
}
else if (col.ColumnName.Equals("Customer"))
{
TemplateField tempColumn = new TemplateField();
tempColumn.HeaderText = col.ColumnName;
tempColumn.ItemTemplate = new LinkButtonTemplate(col.ColumnName,
"~/screent.aspx?nav=1&cid=", "FakID");
grvSearchResult.Columns.Add(tempColumn);
}
else
{
BoundField boundColumn = new BoundField();
boundColumn.DataField = col.ColumnName;

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 LinkButtonTemplate 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.

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 LinkButtonTemplate class in more pages and grids.
Thank you.

Please find fixed code below. Two things, 1. you have to create grid on

event handler, 2. bind data only once (IsPostBack == false)

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;

tempColumn.HeaderText = col.ColumnName;
tempColumn.ItemTemplate = new LinkButtonTemplate(col.ColumnName,
"~/screen.aspx?nav=1&tab=I&cid=", "markID");
grvSearchResult.Columns.Add(tempColumn);

You have to recreate the grid because criteria have changed:
protected void SearchButton_Click(object sender, EventArgs e)
{
string criteria = txtCrieria.Text;
// get data source based on carent criteria
CreateGrid();
}

I understand what you mean with the user control way.
One more thing. This is on a search page and after clicking the search

Then I create the grid.
But that's after the Page_Init and Page_Load.
Is there something I can do about that?
