I have a AutoCompleteBox
My requirement is that I have to disable entering duplicate entries to the rad autocomplete box.
In my case I have a Languages autocomplete box but I am able to enter the item 'English' multiple times.
I want to ensure it is only entered once.
Question: Is there any-way so that if an entry is already there I can remove selected value?

Hi,

When I loop though the Items collection in the RadAutoCompleteBox control, I've noticed the items are ordered alphabetically. Is it possible to receive this collection in the order they are entered in control because this order is important to me. It would be messy if I have to manually delimit the text property to get the item order and then manually match it with each entry in the items collection so that I can retrieve the value of each item as specified in the AutoCompleteValueMember property.

Kind regards.

I'm new to Telerik and still working on the 30 day trial so please bear with me, and pardon the ignorance if this is mind numbingly simple,

 

I need a simple way to show a simple hardcoded dropdown (Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday) which validates input when a user edits the cell of a RadGridView

      private void dg_DeliverySched_beginEdit(object sender, Telerik.WinControls.UI.GridViewCellCancelEventArgs e)
        {
            //I have these columns that need day of week validation comboboxes on edit click
            if (e.Row is GridViewFilteringRowInfo && e.Column.Name == "Sun")
            {
                e.Cancel = true;
            }
            if (e.Row is GridViewFilteringRowInfo && e.Column.Name == "Mon")
            {
                e.Cancel = true;
            }
            if (e.Row is GridViewFilteringRowInfo && e.Column.Name == "Tue")
            {
                e.Cancel = true;
            }
            if (e.Row is GridViewFilteringRowInfo && e.Column.Name == "Wed")
            {
                e.Cancel = true;
            }
            if (e.Row is GridViewFilteringRowInfo && e.Column.Name == "Thu")
            {
                e.Cancel = true;
            }
            if (e.Row is GridViewFilteringRowInfo && e.Column.Name == "Fri")
            {
                e.Cancel = true;
            }
            if (e.Row is GridViewFilteringRowInfo && e.Column.Name == "Sat")
            {
                e.Cancel = true;
            }
        }

Not sure if this is the right place to post, as I am not seeing any specific category for Charts(except the defunct one)

The issue:  I'm building my forst RadChartView based on a simple  query for "Vendor", and "Amount"

Amount, is a decimal in the database, and I'd like to have the Y axis display the values in currency format.

 

I'm not finding how to do this..?

 

Many thanks,

Rich

Hi,

I have a question about IsSelected & IsCurrent.

I have a gridview that when upon loading, the first row is selected and highlighted, so I have a pop-up contatiner that will get the current row data.  But when reload that gridview again, no rows are highlighted any longer.

I've tried IsSelected and IsCurrent, but it only highlights the row with the IsSelected, but when I click on the pop-container that gets the current row data, it gives a error due to null value.

What can I do?

Thanks!

A checkboxdropdownlist is used to filter data for a chart.  After the initial load of list items the first item in the list is selected - even though it is not checked.  Turning it off in code doesn't work either.

 

for (i = 0; i < theRoot.ChildNodes.Count; i++)
{
    ServerName = theRoot.ChildNodes[i].Attributes["Name"].Value;
    foreach (XmlNode aNode in theRoot.ChildNodes[i])
    {
        if (aNode.InnerText == Environment)
        {
            sb = new StringBuilder();
            sb.Append(ServerName.Replace("XX", aNode.InnerText));
            lItem = new Item(j, sb.ToString());
            lvServers.Add(lItem);
            j++;
        }
    }
}
 
rcddlServers.DataSource = lvServers;
rcddlServers.ValueMember = "id";
rcddlServers.DisplayMember = "description";
rcddlServers.DropDownListElement.SelectionMode = SelectionMode.MultiSimple;
if (rcddlServers.SelectedItems.Count > 0) --> why is this possible?
{
    rcddlServers.Items[0].Checked = false;
}

How can I make sure that the control correctly displays percentages greater than 100 (150%, 200% ...)?
