Hi,
In one of a form in our application we have a rad combo which updates itself with data everytime we change some parameters in form. We are using a webservice to get the list of  RadComboItemData and bind on the client side.

When we bind whats happening is that the last selected text still remains visible even if its not in the new list. We have a required field validator for the list. If I manually do select on the first item (First item displays a message that an item must be selected) of the new list using comboItem.Select() it launches validation and dispalys our required field validator that an item must be selected.
 
Is there a proper way of doing it so that new list populates itself without any garbage left over from the last binded data?

My second question is can we do validation on value of the selected item instead of text?

Thanks in advance for your help.

Best regards,
Khurram

Client side binding function

function bindCombo(combo,result){

var items = combo.get_items();

items.clear();

for(var i=0;i< result.length;i++){

var comboItem = new Telerik.Web.UI.RadComboBoxItem();

comboItem.set_text(result[i].Text);

comboItem.set_value(result[i].Value);

items.add(comboItem);

if (i == 0) {

comboItem.select();

}

}

}

 

When you select a file to upload first attach only one photo-Loading and the progress is not displayed. So when you select the file, close the window and back to the normal upload. If you select a file, then upload again reloading the phenomenon of the show will be repeated only. I would like to know why it does this??

Is it possible to switch the view on the Scheduler so that the time is along the top with the days down the side? If it is could you tie this switch to a button control?

I customized the page sized in paging drop down in code behind.

when the user change the paging size to 100 (or lower) it's working.
but when user change the paging size to 200 (or higher) and then try to press on next or different page size nothing happen. the big page size cause the paging mechanism to stuck until i refresh the page.

partial code:

grid.aspx.cs

  protected void RadGrid1_ItemCreated(object sender, Telerik.Web.UI.GridItemEventArgs e)
    {
        //change paging combo value
        if (e.Item is GridPagerItem)
        {
            var dropDown = (RadComboBox)e.Item.FindControl("PageSizeComboBox");
            var totalCount = ((GridPagerItem)e.Item).Paging.DataSourceCount;
            var sizes = new Dictionary<string, string>()
            {
                {"10", "10"},
                {"20", "20"},
                {"50", "50"}
            };
            if (totalCount > 100)
            {
                sizes.Add("100", "100");
            }
            if (totalCount > 200)
            {
                sizes.Add("200", "200");
            }
            if (totalCount > 500)
            {
                sizes.Add("500", "500");
            }

            dropDown.Items.Clear();
            foreach (var size in sizes)
            {
                var cboItem = new RadComboBoxItem() { Text = size.Key, Value = size.Value };
                cboItem.Attributes.Add("ownerTableViewId", e.Item.OwnerTableView.ClientID);
                dropDown.Items.Add(cboItem);
            }
            dropDown.FindItemByValue(e.Item.OwnerTableView.PageSize.ToString()).Selected = true;
        }


    }
