Hello,

  I have radcombobox inside radwindow. When postback occurs, Radcombobox itemsrequested event is called and it would insert the items. I would select the item and display the data. It works up to this point. Now, if I click the radcombobox arrow to select again, it freeze. I have to click outside and select again then it works. also, after item is selected, I can't close the radwindow. I need to click outside again, and the radwindow close button works fine. Why is this happening? Could you provide a fix for this problem? thanks. below is sample code.

//client side

 function RadComboBox1_OnClientSelectedIndexChanged(arg) {
                if (arg) {                
                    __doPostBack("<%=RadComboBox1.UniqueID%>", "OnSelectIndexChange");                  
                }
            }

<telerik:RadAjaxManagerProxy ID="RadAjaxManagerProxy1" runat="server">
<AjaxSettings>
  <telerik:AjaxSetting AjaxControlID="RadComboBox1">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="pnlBox" />                                            
                </UpdatedControls>
            </telerik:AjaxSetting>

</AjaxSettings>
</telerik:RadAjaxManagerProxy>

 <telerik:RadWindowManager ID="RadWindowManager1" runat="server"></telerik:RadWindowManager>

    <telerik:RadWindow ID="RadWindow1" runat="server" >   
 <asp:Panel ID="pnlBox" runat="server">
   <telerik:RadComboBox ID="RadComboBox1" runat="server" EmptyMessage="Select" OnClientSelectedIndexChanged="RadComboBox1_OnClientSelectedIndexChanged"
    OnSelectedIndexChanged="RadComboBox1_SelectedIndexChanged" OnItemsRequested="RadComboBox1_ItemsRequested" EnableScreenBoundaryDetection="false" AutoPostBack="false" >
 </telerik:RadComboBox>
</asp:Panel>
</telerik:RadWindow>

// server side
        protected void RadComboBox1_ItemsRequested(object sender, RadComboBoxItemsRequestedEventArgs e)
        {
            //get items and bind to RadComboBox1;
        }
        protected void RadComboBox1_SelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e)
        {           
            //display data;
        }

Hello,

I was wondering how to limit <asp:DropDownList ... />, that its height would be limited to displayed element count, for example, if there are two elements, list will end after them, if there are three, four and so on. Now, as i understand, list is generated by default for 18 lines, if there are one result, list is still 18 lines long, but almost empty.

Thank you for help.

Milgerdas.

Hello,

I need to fire a server event that will save the grid state  to a database when a grid column is resized.  I have gone through the forums and it seems the way to accomplish is by firing an ajax request, but I can't any sample code that shows how to do do this.  If anyone has expierance with this and could post a code sample, I would really appreciate it.   I am using an AjaxManagerProxy in a user control with the AjaxManager on a master page. 

Thanks,
Bob

Hi,
In my solution i have created Master page with dynamically loaded RadPanel binding with datatable in Codebehind . And used this as Master page to my Child Pages.I have binded the RadPanelItems and assigned the items with Redirection using NavigateUrl Property .
After Navigation from ChildItem of menu click ,i cannot find the Selected item of menu control in the loaded child pages. 
In my scenario i have to get the selected item value in child pages and need to select particular parent item of the child and expand the parent item by code behind.
I have set PersistStateInCookie = true .But i want to select the RadpanelItem and their child item for my application scenarios. Please give me the solution asap.

 

 

 

Thanks.

Hi

I would like to integrate the navigation menu into a site that does not have telerik dlls.  I looked to see if there is a Kendo version of this control but without that I'm back to this one.

In my main site I have it working just fine so that as the page reduces in width items drop into the hamburger (or sandwich) menu.  

I'd like to know what css & js files I would need to use.  I am happy to create this from the client side as this site doesn't have much in the way of .net server side stuff.

Regards

Jon

Hi, I have a situation like this (see the attach image), and I have some dilemma.

I have in my page several radgrids, populated with the Advanced Databinding. I use OnNeedDataSource correctly for taking data from my database.

In my scenario the user can press on the "Add row" button and, through a EditForm, create a new row for the grid. The user can see this row, but this row is not saved immediatly on the database. I want to save this new row (and other changes and informations in the page) only after pressing the Save button.

But I have encountered many problems to do this. For example I have some difficulties with managing rebinds and postback... So, I'm here to ask you if exist some "Best practice" to do this kind of stuff.

Thank you for your attention.

Hello, 

I have a rad grid where grouping is being used.  The first column is a linkbutton which after 1 layer of being clicked into is then replaced with text to both disable and remove the link.  

When I collapse and then re-expand the group the column values are now all gone. 

Prior to collapsing my markup looks like 

<td class="GrdBtn">

<span style="cursor:default;">Sept 2016</span>

</td>

After clicking the collapse and then expanding the markup is 

<td class="GrdBtn">

<a href="javascript:__doPostBack('ReportGrid$ctl00$ctl05$ctl00','')"></a>

</td>

 

I cannot identify an event to which this occurs.  The column is defined in the apsx as 

   <telerik:GridButtonColumn ButtonType="LinkButton" ImageUrl="" HeaderText="Region" DataTextField="RegionName" ItemStyle-CssClass="GrdBtn" CommandName="Select" UniqueName="btnSelect" SortExpression="RegionName" HeaderStyle-Width="150px" />

 

The event to which changes the linkbutton to a span is within the RadGrid_DataBound event and looks like 

btn = CType(CType(Page.Form.FindControl("ReportGrid"), RadGrid).MasterTableView.Items(i).Cells(3).Controls(0), LinkButton)
CType(Page.Form.FindControl("ReportGrid"), RadGrid).MasterTableView.Items(i).Cells(3).Controls.Remove(btn)
Dim finalTxt As String = String.Format("<span style='cursor:default;'>{0}</span> ", btn.Text)
Dim litControl As New LiteralControl(finalTxt)

What event could be causing this?  Or how can i prevent this behavior from happening?
