Here is the UpdateCommand function :

protected void RadGridNomenclature_UpdateCommand(object sender, GridCommandEventArgs e)

{

GridEditableItem item = e.Item as GridEditableItem;

Hashtable newValues = new Hashtable();

e.Item.OwnerTableView.ExtractValuesFromItem(newValues, item);

[...]

}

I can retrieve key and values in the newValues Hashtable.

The same code for the insert commande return me an empty newValues Hashtable.

protected void RadGridNomenclature_InsertCommand(object sender, GridCommandEventArgs e)

{

GridEditableItem item = e.Item as GridEditableItem;

Hashtable newValues = new Hashtable();

e.Item.OwnerTableView.ExtractValuesFromItem(newValues, item);

String desc = newValues["description"].ToString(); // ---------- newValues is Empty ---------------

}

Have you any ideas ?

Is there a way to fire the HeaderContextMenu of a RadGrid based on button click instead of Header right click?
I want to place a button in the header of the grid, once clicked it should open the HeaderContextMenu.

I have a grid in which I display column totals in the footer.
Below is the declaration of my grid column.

<telerik:GridTemplateColumn UniqueName="EndBalance" HeaderText="Ending Balance" ItemStyle-HorizontalAlign="Right"

FooterStyle-HorizontalAlign="Right">

<ItemTemplate>

<asp:HyperLink ID="linkEndBalance" runat="server" Text='<%# Eval("EndBalanceDollars")%>'></asp:HyperLink>

</ItemTemplate>

<FooterTemplate>

<asp:HyperLink ID="linkEndBalanceTotal" runat="server"></asp:HyperLink>

<br />

<asp:HyperLink ID="linkEndBalanceGrandTotal" runat="server"></asp:HyperLink>

</FooterTemplate>

</telerik:GridTemplateColumn>

I am having troubles with the footer when exporting the grid.
The total and the grand total columns overlap each other and are not displayed on separate lines.

I have my exportonlydata set to true.

How can I get the line break in the footer.

Error : Sys.WebForms.PageRequestManagerServerErrorException: Invalid JSON primitive: Rebind.

In one of our project requirement we have customized the SPRADGRID webpart and have created our own webpart. We are facing some issues with Ajax request.

The rad grid is bound to an SharePoint list. and we are calling the ShowEditInsertForm to open the Edit And Add form for the list. when we submit the form. We are trying to refresh the grid through ajax request when the model pop is closed. we get the above mentioned error when the ajax request completes its execution.

below is some part from the code.

Ajax Manager ajax request code
void AjaxManager_AjaxRequest(object sender, AjaxRequestEventArgs e)
{
if (e.Argument == "Rebind")
{
this.Grid.Rebind();
}
}

JavaScript Code to raise the request
function refreshGrid(arg)
{
if (!arg)
{
ajaxManagerClientId = 'ctl00_RadAjaxManager1';
$find(ajaxManagerClientId).ajaxRequest();
}
else
{
ajaxManagerClientId = 'ctl00_RadAjaxManager1';
$find(ajaxManagerClientId).ajaxRequest();
}
}

[Solved] using RadAJAX Manager with RadComboBox Or DropDownList

Hello ,,

I've two RadComboBox one for the Region and the other for the Place,,

    
                            <telerik:RadComboBox ID="ddl_Regions" runat="server" Skin="WebBlue" Filter="Contains" 
        
                                Width="200px" AutoPostBack="True" CssClass="Lists">  
        
                            </telerik:RadComboBox> 
        
                            <telerik:RadComboBox ID="ddl_Places" runat="server" Skin="WebBlue" Filter="Contains" 
        
                                Width="200px" CssClass="Lists">  
        
                            </telerik:RadComboBox>

When the user choose a Region the Place list will rebind and get the Places of the selected Region

    
                                Dim Places As New BusinessLayer.Placess  
        
                                Places.GetByRegionID(ddl_Regions.SelectedValue)  
        
                                ddl_Places.DataSource = Places  
        
                                ddl_Places.DataTextField = "Name" 
        
                                ddl_Places.DataValueField = "ID" 
        
                                ddl_Places.DataBind()

everything was fine until i put the Region

    
            <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" OnAjaxRequest="RadAjaxManager1_AjaxRequest">  
        
                <AjaxSettings> 
        
                    <telerik:AjaxSetting AjaxControlID="RadAjaxManager1">  
        
                        <UpdatedControls> 
        
                            <telerik:AjaxUpdatedControl ControlID="ddl_Regions" /> 
        
                            <telerik:AjaxUpdatedControl ControlID="ddl_Places" /> 
        
                            <telerik:AjaxUpdatedControl ControlID="lbl_result" /> 
        
                        </UpdatedControls> 
        
                    </telerik:AjaxSetting> 
        
                </AjaxSettings> 
        
            </telerik:RadAjaxManager>

when I did that the application still enter the selectedIndexChanged Event of the ddl_Regions and rebind the places but the ddl_Places does't refresh until i did a postback

Should i do postback everytime i want to rebind the ddl_Places data ,?,, what's the best way to achieve this?

Thank for help

Tabs Based on Date Passed in QueryString

I'm interested in building a tab strip that will dynamically change based on a value passed in a querystring, such as a date.
The current date will be highlighted in the tab and multiple days on either side of the center tab will show.
I've attached a screen shot of what I'd like to do and I didn't know if there's a similar example out there.

Thanks,
Matt

RadComboBox ajax client side encoding

Im facing a problem with encoding of RadComboBox.

Before postback in Viewstate I have:

ctl00_plhBody_ctrRegistration_cbBoss_ClientState:{"logEntries":[],"value":"20","text":"Андреев","enabled":true}

And after postback there is:

{"logEntries":[],"value":"20","text":"Андреев","enabled":true}<br>

And then application crashes. Its in updatePanel, and unfortunately I dont have error message (its on productioin right now and Ive got limited access to logs).

Thanks for any suggestions
