<telerik:RadGrid ID="RadGrid1" runat="server" GridLines="None" OnItemDataBound="RadGrid1_ItemDataBound" OnItemCreated="RadGrid1_ItemCreated" OnColumnCreated="RadGrid1_ColumnCreated"AllowAutomaticInserts="true" OnNeedDataSource="RadGrid1_NeedDataSource" Skin="Office2007"AutoGenerateColumns="true">

<NoRecordsTemplate>

There isn't any data.</NoRecordsTemplate>

</MasterTableView>

<ClientSettings EnablePostBackOnRowClick="true" />

</telerik:RadGrid>

<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ChalkHillConnectionString3 %>"

SelectCommand="SELECT [ProductName] FROM [tblProducts]"></asp:SqlDataSource>

C# is

protected void Page_Load(object sender, EventArgs e)

{

if (!IsPostBack)

{

//AddValuesToItemsDropdown();

RadGrid1.Visible = true;

}

protected void ddlItems_SelectedIndexChanged(object sender, EventArgs e)

{

DropDownList ddlItems = (DropDownList)sender;

GridEditFormItem editItem = (GridEditFormItem)ddlItems.NamingContainer;

GridDataItem item = (GridDataItem)editItem.ParentItem; // access GridDataItem

Label lblRate = (Label)item.FindControl("lblRate"); // access Label using DataItem

if (ddlItems.SelectedIndex > 0)

{

DataSet ds = objSQLHelper.GetProductDetails("select * from tblProducts where Pid=" + ddlItems.SelectedValue);

if (ds != null)

{

lblRate.Text = ds.Tables[0].Rows[0]["Rate"].ToString();

}

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)

{

if ((e.Item is GridEditFormItem) && (e.Item.IsInEditMode))

{

GridEditFormItem editform = (GridEditFormItem)e.Item;

e.Item.Edit = true;

DropDownList ddlItems = (DropDownList)editform.FindControl("ddlItems");

ddlItems.DataSource = ds;

ddlItems.DataTextField = "ProductName";

ddlItems.DataValueField = "Pid";

ddlItems.DataBind();

}

private void RadGrid1_PreRender(object sender, System.EventArgs e)

{

if (!IsPostBack)

{

foreach (GridItem item in RadGrid1.MasterTableView.Items)

{

if (item is GridEditableItem)

{

GridEditableItem editableItem = item as GridDataItem;

editableItem.Edit = true;

}

RadGrid1.Rebind();

}

Why is Grid not visible on page load?....
