[Solved] Item Not Being Selected

[Pradeep]

Hello,

I have an Edit button located on my MasterPage and a RadGrid located in my Default.aspx page. I am trying to get the Session ID of the row selected in the Default.aspx page and pull in those values into my Edit page.
When I select a row in Default.aspx and then click Edit, the page refreshes and the row is deselected.
What am I doing wrong here?

Here is my code behind for the MasterPage Edit button:

protected void lEditItem_Click(object sender, EventArgs e)
{
    GetSelected();
    if (Session["CriteriaID"] != null)
    {
        Session["AccessMode"] = "";
        Response.Redirect("~/EditCriteria.aspx");
    }
}

private void GetSelected()
{
    RadGrid control = (RadGrid)PageContent.FindControl("criteriaList");
    foreach (GridDataItem item in control.MasterTableView.Items)
    {
        if (item.Selected)
        {
            String temp = item.GetDataKeyValue("ID").ToString();
            Session["CriteriaID"] = new Guid(item.GetDataKeyValue("ID").ToString());

        }
    }
}

The code for the RadGrid in Default.aspx is

<asp:Content ID="Content2" ContentPlaceHolderID="PageContent" runat="server">
    <div class="PageBlock">
            <div class="SecHeader">Criteria List</div>
    <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:CriteriaCS %>"

Hello Pradeep,

It is preferable to extract the id when the grid row is clicked. You can achieve this by handling the OnItemCommand of the grid. This is also demonstrate in the code snippet below:

protected void RadGrid1_ItemCommand(object sender, Telerik.Web.UI.GridCommandEventArgs e)
    {
        if (e.CommandName == "RowClick")
        {
            Session["CriteriaID"] = (e.Item as GridDataItem).GetDataKeyValue("ID").ToString();
        }
    }

Later when the button in the master page is clicked you can extract the value directly from the session variable.

protected void lEditItem_Click(object sender, EventArgs e)
    {
        if (Session["CriteriaID"] != null)
        {
            string id = Session["CriteriaID"].ToString();
        }
    }

Thanks for the reply!

Actually, I had created an OnClick event for the button and deleted it from the *.cs file, but I didn't remove the OnClick ID from the .aspx file. So, when clicking, a non-existing event was occurring, which disrupted the GetSelected() process.

Thank you again for taking the time to reply!
