Hi,

i am Dynamically creating bound fields and hyperlink field for the gridview.

so once the data is bound the gridview displays the day which contains bound field as well as hyperlink.
my problem is when i click on hyperlinkfield it has to redirect to the other page carrying the Identity value of the table
i have also tried giving datakey names but unable to access them

here is my code

if (item.Text == "CompanyName")
                 {
                     //string id = gdvCompanies.SelectedDataKey.Value.ToString();
                     HyperLinkField hl = new HyperLinkField();
                     //hl.Click = new EventHandler(hl_Click);
                     hl.DataTextField = item.Value;
                     hl.HeaderText = item.Value;
                     //hl.Click += new EventHandler(clickMe);
                     hl.NavigateUrl = "EditCompany.aspx?&CID={1}";

                     gdvCompanies.Columns.Add(hl);
                 }
                 else
                 {
                     BoundField b = new BoundField();
                     b.DataField = item.Value;
                     b.HeaderText = item.Value;
                     gdvCompanies.Columns.Add(b);
                 }

Solution 1

You use the RowDataBound event of your Gridview.

protected void OnRowDataBound(object sender, GridViewRowEventArgs e)
{
    ...

    //get the DataItem
    DataRowView rowView = (DataRowView)e.Row.DataItem;
    if(!string.IsNullOrWhitespace(rowView["CID"].ToString())
        hl.NavigateUrl = "EditCompany.aspx?CID=" + rowView["CID"].ToString();

    ...
}

But i have a problem executing the above procedure.
My first column data in the gridview is not working. i mean the hyperlink field is not working for the first column hyperlinkfield

Then CID is null and the Hyperlink Navigate URL isn't being populated correctly. Create a default URL if CID is empty to populate.
