How do I pass querystring from the detailsview update?

Dear Experts,

I have this DetailsView with ShowEditButton set to true. When user click Update, I need to pass a querystring from inside the EditItemTemplate, the value of the querystring should be from one of the dropdown selectedvalue. How can I do that?

You want to pass querystring to what?
You can definitely grab the value of dropdown something like this in the DV ItemUpdating event that is fired when you click the Update button:

protected void DetailsView1_ItemUpdating(object sender, DetailsViewUpdateEventArgs e)
        DropDownList ddl = (DropDownList )DetailsView1.FindControl("DropDownList 1");
        string value = ddl.SelectedValue;

       //OR try getting new value using correct index / name of your ddl field
        string newvalue = e.NewValues[1].ToString();

       //you can use this value to pass it to querystring

I use this:

protected void DetailsViewAuditEdit_ItemUpdated(Object sender, System.Web.UI.WebControls.DetailsViewUpdatedEventArgs e)
        DropDownList ddl = (DropDownList)DetailsViewAuditEdit.FindControl("lstBranch");
        string value = ddl.SelectedValue;
        //pass the query string

And it works. That's what I was looking for. Thanks.
