[Solved] Check column for combobox text

[Tracey Kroll]

I have a RadGrid with a RadComboBox and linkbutton in a footer template of a GridTemplateColumn. When the linkbutton is clicked  I want to check if the value selected in the combobox exists in a particular column in the grid. Does anyone know how I can accomplish this with Javascript? Thanks in advance!

Hi Tracery,

One suggestion is you can attach the OnClientSelectionIndexChanged event to RadComboBox and proced to searching the value in particular column instead of using extra Linkbutton. I tried following client side code for this. Please give a try wiith this and see whether its suitable for you.

<telerik:GridTemplateColumn HeaderText="Action" UniqueName="TemplateColumn" >
   <ItemTemplate>
     <%# Eval("CategoryName") %>
   </ItemTemplate>
   <FooterTemplate>
    <telerik:RadComboBox  runat="server" ID="RadComboBox1" OnClientSelectedIndexChanged="OnClientSelectedIndexChanged">
        <Items>
            <telerik:RadComboBoxItem Text="Produce" />
            <telerik:RadComboBoxItem Text="Beverages" />
        </Items>
    </telerik:RadComboBox>
   </FooterTemplate>
</telerik:GridTemplateColumn>

[javascript]

<script type="text/javascript">
function OnClientSelectedIndexChanged(sender, args)
{
    var text = sender.get_text();
    var firstDataItem = $find("<%=RadGrid1.ClientID %>").get_masterTableView().get_dataItems()[0];
    var number = $find("RadGrid1").get_masterTableView().get_dataItems().length;
    var MasterTable = $find("<%=RadGrid1.ClientID %>").get_masterTableView();
    for(i=0; i<number; i++)
    {
        var row = MasterTable.get_dataItems()[i];
        var cell = MasterTable.getCellByColumnUniqueName(row, "CategoryName");
        if(cell.innerHTML == text)
        {
            alert('Exists, Row number : '+ (i+1));
        }
    }
}
</script>

Thanks,
Shinu.

I actually needed the link button for other reasons but was able to make a slight modification to your code to get exactly what I needed. Thanks so much!!!
