Pass variable to another page

fergus

ok so i have a page with a gridview on it and it displays rows from sql table. i have also a link assigned to each row:

this works fine and the url that gets displayed is good. But i would like to send the our_ref attribute to the page itself aswell as the url and use it make further queries.

Thanks

To achieve this functionality, you can utilize the RowCommand event of the GridView. When the hyperlink is clicked, the RowCommand event is triggered, allowing you to access the row data and redirect to the target page with the necessary parameter.
```
protected void GridViewMatters_RowCommand(object sender, GridViewCommandEventArgs e)
{
    if (e.CommandName == "ViewDetails")
    {
        int rowIndex = Convert.ToInt32(e.CommandArgument);
        GridViewRow row = GridViewMatters.Rows[rowIndex];
        string ourRef = row.Cells[1].Text; // Assuming 'our_ref' is in the second cell

        // Redirect to the target page with the parameter
        Response.Redirect("MD_Overall.aspx?id=" + ourRef);
    }
}
```
In your GridView markup, modify the HyperLink control to trigger the RowCommand event:
By using the RowCommand event and passing the row index as the CommandArgument, you can retrieve the necessary data from the GridView row and redirect to the target page with the parameter included in the URL.

To pass the our_ref attribute to the destination page, you can use either the query string or session variables. Here's how you can do it using a query string:
Then, on the destination page (MD_Overall.aspx), you can retrieve the our_ref value from the query string:
```
protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        if (Request.QueryString["our_ref"] != null)
        {
            string ourRef = Request.QueryString["our_ref"];
            // Use the ourRef value to make further queries or operations
        }
    }
}
```
