RadComboBox in RadTooltipManager

[Alexey]

Hi All,

I have a problem with RadComboBox and setting SelectedIndex value.

My controls structure are next:

<telerik:RadToolTipManager ID="editRecordTooltip" ShowEvent="OnClick" OffsetY="-1" HideEvent="ManualClose" Modal="true"
    Width="470" Height="390" runat="server" EnableShadow="true" OnAjaxUpdate="OnAjaxUpdate" RelativeTo="Element"
    Position="MiddleRight">                                
</telerik:RadToolTipManager>
 
<telerik:RadGrid ID="rgRecords" AutoGenerateColumns="false" runat="server" OnItemDataBound="rgRecords_ItemDataBound">
    <MasterTableView DataKeyNames="ID">
        <Columns>
            ..... 
         </Columns>
    </MasterTableView>
</telerik:RadGrid>


 protected void OnAjaxUpdate(object sender, ToolTipUpdateEventArgs args)
 {
     UpdateToolTip(args.Value, args.UpdatePanel);
 }

private void UpdateToolTip(string elementId, UpdatePanel panel)
{            
   Control ctrl = Page.LoadControl("EditRecord.ascx");
   panel.ContentTemplateContainer.Controls.Add(ctrl);
}

protected void rgRecords_ItemDataBound(object sender, GridItemEventArgs e)
        {
            if (e.Item.ItemType == GridItemType.Item || e.Item.ItemType == GridItemType.AlternatingItem)
            {
                var target = e.Item.FindControl("hlEdit");
                editRecordTooltip.TargetControls.Add(target.ClientID, (e.Item as GridDataItem).GetDataKeyValue("ID").ToString(), true);
            }
        }

EditRecord.ascx contains:

<telerik:RadComboBox runat="server" ID="rcbCompany" Filter="Contains" ZIndex="50001" Width="234px" CssClass="select-text" />

protected override void OnPreRender(EventArgs e)
{
   base.OnPreRender(e);
   
   
   rcbCompany.DataSource = Source;
   rcbCompany.DataValueField = "ID";
   rcbCompany.DataTextField = "Name";
   rcbCompany.DataBind();
rcbCompany.SelectedIndex = 10; // for example
   this.DataBind();

}

When I set rcbCompany.SelectedIndex = 10, it does not worked.
On front-end selectedindex is always -1.

But, standart DropDownList worked perfectly.

How I can set SelectedIndex?

Thanks

Hello Alexey,

Please try removing the this.DataBind() method invocation from your code and let us know the result:

rcbCompany.DataSource = CreateDataSource();
rcbCompany.DataValueField = "ID";
rcbCompany.DataTextField = "Name";
rcbCompany.DataBind();

rcbCompany.SelectedIndex = 10; // for example

//this.DataBind();

All the best,

Hi Kalina,

>Please try removing the this.DataBind() method invocation from your code and let us know the result

It's worked, but with the bug.

rcbCompany.DataSource = CreateDataSource();

rcbCompany.DataValueField = "ID";

rcbCompany.DataTextField = "Name";

rcbCompany.DataBind();

if (somevalue) 

   rcbCompany.SelectedIndex = 10; // for example

 

I have a grid with several records, where somevalue=true or somevalue=false.

In this case when I open tooltip with somevalue=true it's worked, but when I open tooltip with somevalue=false, after 
tooltip with somevalue=true, than rcbCompany.SelectedIndex == 10 on front-end, but should be == -1.

When I try this solution:

rcbCompany.DataSource = CreateDataSource();

rcbCompany.DataValueField = "ID";

rcbCompany.DataTextField = "Name";

rcbCompany.DataBind();

this.DataBind();

if (somevalue) 

   rcbCompany.SelectedIndex = 10; // for example

All worked perfectly.
