Here is what is working:
I have a RadGrid with a single MasterTableView, loading data from a database table.
Users are able to edit the data using a WebUserControl:
                <EditFormSettings UserControlName="JIBCoding.ascx" EditFormType="WebUserControl" PopUpSettings-Height="600" PopUpSettings-Width="1000">
                    <EditColumn UniqueName="order_by">
                    </EditColumn>
                </EditFormSettings>
The Edit form appears, the user can edit the data, press the "Update" button, which triggers the 'OnUpdateCommand="RadGrid1_UpdateCommand"' to reflect the edited data in the grid and update the database.
All this works fine.

However, I need to be able to perform some validation on the data entered by the user before the Update sequence starts.
If the validation fails, I want to display an alert with an error message, and with the WebUserControl form to remain displayed, with the data as entered by the user. Basically intercept the "update" sequence.

As a result, I have been trying to figure out how to programmatically fire the "Update" comment from Javascript, and I can't figure out what I'm doing wrong.
I've been basing my attempts on the following post:
https://www.telerik.com/forums/calling-the-itemcommand-handler-from-javascript

In my Grid.aspx code, I have the following Javascript code:
<script>
    var varRadGrid;
    function GridCreated(sender, eventArgs) {
        varRadGrid = sender;
    }
    function CallUpdate() {
        var masterTable = varRadGrid.get_masterTableView();
        masterTable.fireCommand("Update", "");
    }
</script>

In my WebUserControl code, I have added a "Validate/update" button to call the "CallUpdate" function:
            <asp:Button ID="button" runat="server" Text="validate/update" OnClientClick="javascript:CallUpdate();" />

I can trace through that all the various pieces appear to be working:
1. When the grid initially loads, a reference to it is captured in varRadGrid.
2. When the user presses the "Validate/update" button, the CallUpdate function is called, and it is able to reference the varRadGrid object.
3. However, the code ' masterTable.fireCommand("Update", ""); ' appears to not do anything.
Actually, that's not true - the WebUserControl form closes, but then is immediately redisplayed.

Any edited data is not reflected back in the underlying grid - the "Update" command doesn't appear to be being fired.

Any ideas? Help much appreciated!!

Hi All, 

 

i have a grid view and i want to have 2 question first how can i fill the drop down with data table from the c# 2nd how can i do it cascading from the c# too i will make it onselected item change but can i find the secound dropdown menu to auto fill with the new dropdown list 

 

 

ps <br> is not there its just added by code format :)

 

How can I replace expand/collapse images of Radpanel item with some other images when RenderMode="Lightweight" ?

On expand I need to show different image and On collapse I need to show another image.

 

Below solution is not working for me because I think skin file selector is not supporting.

 

<style>
    .t-i-expand-s:before, .t-i-expand-down:before, .p-i-expand-s:before, .p-i-expand-down:before, .p-i-arrow-chevron-down:before {
        content: "\e100" !important;
    }

    .t-i-expand-n:before, .t-i-expand-up:before, .p-i-expand-n:before, .p-i-expand-up:before, .p-i-arrow-chevron-up:before {
        content: "\e101" !important;
    }
</style>

 

 

Right now my selector is like

 

.RadPanelBar .rpExpandable .rpExpandHandle 

{

display : block;

}

 

 

I have the following problem, I check the documentation and several samples for hours, I attach the images on the aligned RadMenuItem  and left position, whatever the click I need the position the first o second row the RadMenuItem should be aligned to left

In the following line of code does not allow to select the second row of the menu

.infoenergy .RadMenu_Glow .rmHorizontal .rmItem {
    position: static;
}

I'm trying to databind the pie chart to the sqldatasource, but it seems there are issues (or I'm not doing it right) with DataFieldY.  The sqldatasource will return 2 column of data as follow:
Description     cnt
7 Days            3
30 Days        37
Rest              42
24 Hour         116

Where the "Description" column I assign to "NameField" and "cnt" column I assign to DataFieldY.  Below is my code for the chart.
                            <telerik:RadHtmlChart runat="server" ID="chartRouters" Width="100%" Height="100%" Transitions="true" 
                                Skin="Silk" DataSourceID="sqlDSModem">
                                <ChartTitle Text="Router Status">
                                    <Appearance Align="Center" Position="Top">
                                        <TextStyle Color="White" />
                                    </Appearance>
                                </ChartTitle>
                                <Legend>
                                    <Appearance Position="Right" Visible="true">
                                    </Appearance>
                                </Legend>
                                <PlotArea>
                                    <Series>
                                        <telerik:PieSeries StartAngle="90" DataFieldY="Cnt" NameField="Description">
                                            <LabelsAppearance Position="OutsideEnd" DataFormatString="{0} %">
                                            </LabelsAppearance>
                                            <TooltipsAppearance Color="White" DataFormatString="{0} %"></TooltipsAppearance>
                                        </telerik:PieSeries>
                                    </Series>
                                </PlotArea>
                            </telerik:RadHtmlChart>   

when I run the code, my pie chart looked "weird" and had only 4 lines (not the chart line, but lines extending out from a single point) Looks almost lilke it is not reading the "cnt" column of the data.  

When I go to the immediate window and do the :

?chartRouters.PlotArea.Series(0).DataFieldY(0)

 

it gave me value of "c" and then DataFieldY(1) is "n" and DataField(2) is "t".  I was expecting to see the actual value when I do that, but it almost like is putting the column field name in the value instead of actual data value?  That is weird.

What is wrong?

thank you!

How do you clear the selection or go back to intial state via javascript?  I can do it from codebehind but it's faster on the client side.

Thanks,

Tim

Few parts of my web.config are as follows:

I've found that RadGrid filtering doesn't work when the values have a "<" (less than) character inside of the column.  Upon removing the values with the "<" sign, the filters work.  Does anyone know a fix or way around this?  It seems like an escaping bug.

Thanks,
Jason

radGrid1.ExportSettings.Excel.Format = GridExcelExportFormat.Biff;

I want the format to be Xlsx.  But it only shows Biff, ExcelML, Html as selection.  My references of Telerk.Web.UI is pointing to

C:\Program Files (x86)\Progress\Telerik UI for ASP.NET AJAX R3 2017\Bin35\Telerik.Web.UI.dll

What do I miss?  Thanks.

We are looking to create a custom SharePoint web part which displays appointment data on a Scheduler. Ideally we want to return JSON format data from a WCF service and bind this to the Scheduler. We do not need to use insert / update functionality. Having had a look at some examples we're not sure where to go with this. We've looked into Data Providers but again we haven't been able to successfully implement this so far. Any help / step by step examples would be greatly appreciated.

Thanks
