Any specific reason you are using a hiddenfield instead of boundfield with visible false?

Solution 2

you can set visibility false from client side

C#

//Condition when you want to hide
IdOfGrid.Columns[2].Visible = false; 
// i am supposing it is your second column if not you can change it from 2 to whatever column it is

Hello ,

You can use Label instead on Hidden Field . then set

<asp:TemplateField Visible = "false" >

to get the Label value use this

Label  ID = dgvrow.Cells[6].FindControl("lblid") as Label;
//if lblid is label name and it is in 6th position
 if (ID != null)
int id = Convert.ToInt32(ID.Text);

and use this

id

value for further progress.

thanks

You should hide the Column. Don't set Visibility to false, otherwise it won't render the control.

Write below code in GridView RowCreated Event.
Here Cell 0 means first Column is used. You have to replace 0 with your required Column index.

C#

protected void OnRowCreated(object sender, GridViewRowEventArgs e)
{
     if (e.Row.RowType == DataControlRowType.DataRow)
     {
         e.Row.Cells[0].CssClass = "hiddencol";
     }
     else if (e.Row.RowType == DataControlRowType.Header)
     {
         e.Row.Cells[0].CssClass = "hiddencol";
     }
}

Write the following CSS on the aspx page.

CSS

.hiddencol
 {
     display:none;
 }
