Update text of label in CommandItemTemplate

[Chris LaFrancis]

I have a grid that has 2 labels in the CommandItemTemplate. I also have a RadWindow that I use for a user to set the upper and lower limit values to use on a couple of columns in the grid. When the RadWindow closes I want to take teh values from that window and update the text int he CommandItemTemplate.
My values are returning from the RadWindow correctly and they are being put into 2 variables - lowerLimit and upperLimit.
The label fields on the CommandItemTemplate are:

<

 

asp:Label ID="lblLLimit" runat="server" Text="= over 85%"></asp:Label>

 

<

 

asp:Label ID="lblULimit" runat="server" Text="= over 100%"></asp:Label>

 

How can I update the labels text to display the values returned from the RadWindow programatically?
Thank you very much for your help.

Hello Chris,

You can attach OnClientClose event to RadWindow and get the parameters passed from the window. Then invoke an ajaxRequest() and pass the values to code behind.

<script type="text/javascript">

function ClientClose() {

var lowerLimit = 1; // Get the parameters

var upperLi8mt = 10; // Get the parameters

var myValues = new Array();

myValues[0] = lowerLimit;

myValues[1] = upperLi8mt;

var ajaxManager = $find("<%= RadAjaxManager1.ClientID %>");

ajaxManager.ajaxRequest(myValues); // invoke ajaxRequest explicitly

}

</script>

In the RadAjaxManager1_AjaxRequest event, access the Lables placed in the CommandItemTemplate and set the Text according to the values passed.
CS:

protected void RadAjaxManager1_AjaxRequest1(object sender, AjaxRequestEventArgs e)

{

string values = e.Argument;  // Get the argument passed

string[] array;

array = values.Split(',');

GridCommandItem cmditem = (GridCommandItem)RadGrid1.MasterTableView.GetItems(GridItemType.CommandItem)[0];

{

Label lb1 = (Label)cmditem.FindControl("Label1");

lb1.Text = array[0];

Label lb2 = (Label)cmditem.FindControl("Label2");

lb2.Text = array[1];

}

}

Also set the AjaxSettings accordingly.
ASPX:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" OnAjaxRequest="RadAjaxManager1_AjaxRequest1">
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="RadAjaxManager1">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="RadGrid1" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManager>
