Yeah I saw, why you are not using hyperlink instead of link, you can achieve that things easily. or pass argument command for each link and then use link on click event.

Solution 2

Hi,
try this.

C#

// in code behind
HtmlAnchor Link = (HtmlAnchor)lDgModel.FindControl("Link");
string Link1 = Link.Href; // here store navigate url in string variable

Hope it helps you.

EDIT

C#

foreach (GridViewRow fvr in lDgModel.Rows) // i assume lDgModel is your gridview id
{
    HtmlAnchor Link = (HtmlAnchor)lDgModel.FindControl("fvr");
    string Link1 = Link.Href;
}
// also keep runat="server" in a tag.

it is giving error when i am using runat="server" and "Object reference not set to an instance of an object." when not giving runat="server"

Harshil_Raval 11-Dec-13 7:06am

To access any control one must have runat="server". otherwise it will not access on code behind.

write2varun 11-Dec-13 7:15am

its giving error when im applying runat server

Harshil_Raval 11-Dec-13 7:18am

ok.
in which method you are calling this..
HtmlAnchor Link = (HtmlAnchor)lDgModel.FindControl("Link");

write2varun 11-Dec-13 7:18am

private DataTable GetDataFromGrid()

Harshil_Raval 11-Dec-13 7:20am

it should be in onrowdatabound or onrowcommand events..

write2varun 11-Dec-13 7:23am

im extracting the data like this
foreach (DataGridItem gridmodelin grid.Items)
{
...
...
...
}
