RadGrid Self-referencing Hierarchy - Editing problems
Hi,

I'e followed this demo to get a treeview-like radgrid:
http://demos.telerik.com/aspnet-ajax/grid/examples/hierarchy/selfreferencing/defaultcs.aspx

But the problems start at editing already inserted items.
Only the root(top-parent) item can be edited. If I click on the edit pencil icon on an item that has a parrent, that item dissapears from the gird, but if I later click on a root item both items get opened for editing.
Editing mode is on PopUp with user control.

And here is the page:

Internet Explorer cannot display the webpage
Hi,

I believe I've followed the getting started correctly, but once I've selected a file to upload and click on the Submit button, I get

Internet Explorer cannot display the webpage

shown and the upload has not happened.

I expect I've missed a stage or something, but cannot work out what it is.

Any suggestions welcomed.

ExportOnlyData=&quot;true&quot; causes null reference exception

            </telerik:GridBoundColumn> 
        </Columns> 
    </MasterTableView> 
</telerik:RadGrid> 


I am using advanced databinding for my datasource, but I have noticed that the NeedsDataSource event never fires when I try to export only data:

        protected void grdResults_NeedDataSource(object sender, Telerik.Web.UI.GridNeedDataSourceEventArgs e) 
        { 
            EmployeeSearchCriteriaDTO criteria = SessionManager.SM.EmployeeSearchCriteria; 
 
            if (criteria != null) 
            { 
                IList<EmployeeSearchResultDTO> temp = EmployeeSearchManager.Query2(criteria); 
 
                if (SessionManager.SM.ComparisonUserIDs != null) 
                { 
                    foreach (int id in SessionManager.SM.ComparisonUserIDs) 
                    { 
                        EmployeeSearchResultDTO user = temp.FirstOrDefault(r => r.UserId == id); 
                        if (user != null) 
                            user.Selected = true; 
                    } 
                } 
                grdResults.DataSource = temp; 
            } 
        } 

Any ideas?

[Solved] Missing Ajax RadButton Control?
Hi,

I am evaluating the ASP.NET Ajax controls and can't seem to find a button control (checkbox either), am I missing something?
Where the question comes from is the fact that I am looking into the Skins manager which is very easy to use with RadXXX controls (no code required) but not so easy with .net controls (not even sure it's possible)
Any advice/input welcome

Validation in Usercontrol using RadAjaxManager
Hi,
   I am using RadTabStrip and in that I have multiple tabs. I am also using RadAjaxManager.
   In one of the tabs I have a grid which is enclosed in RadAjaxPanel.   On clicking the Add link of the grid a user control pops-up and will insert a record successfully.

   The problem I am facing currently is with the validations
    Currently I am enclosing the ValidationSummary in a DIV and the DIV is hidden by default,
    OnClientClick event is fired when User clicks on Add button to check if there are any validations errors and if yes gets the innerHTML of the div and displays it using radalert.
    But my Page_ClientValidate("vgVendor") always returns true and I also observed that on clicking the Add button first time the Div.innerHTML does not have the error message but 2nd time it has the error message in it. Page_ClientValidate("vgVendor") always returns true.

Can you please help me on this.

Thanks in advance
Pradeep.

Returning values to parent page from rad window.

Hello all,
               I have a common scenario, but i could not implement in a cleaner way.
 
I have web page which contains a treeview and 2 grid.On clicking each node in tree view shows two grids on right hand side of the treeview populated with values related to the clicked node in treeview. Now on right clicking the node in tree view and selecting a context menu item will open a new rad window for me.

In the rad window the user will make update/insert/delete operations against database. The user can close this rad window in two ways - one is clicking the 'close' button in rad window
-second is clicking the 'X' button on top right corner of rad window.

what i need to do is 'onclientclose' of radwindow, i need to read the arguments that are passed from radwindow and depending on those passed arguments, i have to refresh the treeview as well as the two grids on the parent page. I'm able to achieve this when user clicks 'close' button on radwindow, but when user clicks the 'X' i cannot get the arguments passed back from rad window to parent page. Could anybody please help me in this case?

when user clicks close button on rad window, this is how i'm closing rad window and passing back arguments

 

 

var oArg = new Object();

 

oArg.ReloadGrids = true;

 

oArg.ReloadTreeView= false;
RadWindow.close(oArg);

and on client close this is how i read arguments passed from rad window

 

function

 

 RadWindow_OnClientClose(oRadWind, args) {

 

 

//get the transfered arguments

 

 

var arg = args.get_argument();

 

}


Please let me know if you guys need some more info..

 

cheers!

pravin.

Grid Client Side InLine Edit

Hi,

                We arein process of evaluating new Telerik Grid for our application. While we couldsee great performance improvement using the client side data binding (JSONapproach). Still we are not able to get the inline edit & Add functionalitylike that we have in the Server side bound version. Just curious to know isthere something that we could get the inline edit & add in the client version.

http://www.sigmawidgets.com/products/sigma_grid2/demos/example_column_editor.html

                I gotthis link and the control displayed in the page is very impressive, though I amnot looking for the cell level edit. I am looking for a row inline edit that isfast as this control version.

                Anyoneplease guide me on, is there any out of the box feature /  work around that will get me similarfunctionality.

Thanks

[Solved] How to add title tag to LinkButton Column?
Hi,

I have the following Column:
protected static void CreateAndAddRadGridAuditViewCommandColumn(RadGrid grid)  
{  
    GridButtonColumn auditColumn = new GridButtonColumn()  
    {  
        UniqueName = "AuditView",  
        ButtonType = GridButtonColumnType.LinkButton,  
        Text = "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;" // just make background image from css class visible (using CSS sprites)  
    }; 
    column.HeaderStyle.CssClass = "rgHeader " + "cms-column-auditview";  
    column.ItemStyle.CssClass = newCssClass; 
    grid.Columns.Add(auditColumn); 
}  


The corresponding CSS class is:
.cms-column-auditview a { 
    text-decoration: none !important; 
    background: url(/Cms/Resources/Images/iconset.png) 0px -2032px no-repeat; 
}

Now I want to add a mouseover hint to those images using a "Title" attribute on the link that is rendered.
I need to use CSS sprites for performance reasons. How can I achieve this?

Regards,

   Sebastian
