Hi,
I am using RadGrid from telerik version 2012.1.215.40.

I have two methods RadGrid_NeedDataSource and Page_Prerender event

I am trying to hide AddNewrecordButton based on user permissions


This code doesn't hide the AddNewRecordButton from the grid.
But if i write the same code in RadGrid_NeedsdataSource event, it works. I also tried radGrid_PreRender event but that also not working.
If i add RadGrid.Rebind() method in prerender event, it works. But it fires the NeedsdataSource event again that i don't want.
All my code to hide/show controls based on the permissions is inside the PreRender event. So i don't want to use NeedsDataSource event just for hide/show of Add new record button.
Please suggest what is wrong with the PreRender event.

Hi Team,
            1) We are using RadGrid in our application, we plan to use the In-built functionality from Telerik Radgrid for Exporting the Grid data to Word document and PDF format document. We have Grid data, and Chart Image for the corresponding Grid Data which we displaying outside the Grid. I have attached the Screenshot of my application, I need to populate the Chart Image along with the Grid Data to word document and pdf document while export.  (attached file Name: Application_ScreenShot.JPG)

            2) Also I would like to know that Isn't it possible to export the Grid data with skin(font color,fort size,font family) to Word and Excel and PDF format.

            3) While I tried to Export into PDF format, the Grid Data is not populating properly. Kindly find the attached file for get me.(attached File Name for reference: PDF.JPG)

Please give me any possible solution on this ASAP.

Thanks
Alexis

Hi,
I have a 3 level hierarchical grid.It is populated programatically (i.e. through 'DetailTableDataBind')

Each row in the middle-level grid has a hyperlink, which if pressed causes a dialog to be displayed (through RadWindowManager).

When the dialog is closed (by clicking 'Save'), the dialog closed, and calls a 'refreshGrid' function in the parent.

The 'refreshGrid' then does a 'ajaxRequest("RebindAndNavigate")'.

All pretty standard stuff, except it doesn't seem to refresh the contents of the 3rd level grid.

Am I missing something- does the rebind refresh all displayed 'programmatic-populated' children tables?

Cheers,
Steve

Hi Team,
I have a radgrid which I want to refresh when File Save Dialogue box is closed.

This is my code behind.



If I comment this code to open save file dailogue box, grid gets refreshed. There is some prob with that code..
Could you help me out ?

Thanks,
Lok..

I have a RadAjaxManager, which should update a label on click of a button (simplest of tasks I assume.)

<telerik:RadAjaxLoadingPanel ID="AjaxLoadingPanel1" runat="server" Height="75px" Width="75px">

<asp:Label runat="server" ID="lblTest" Text="appears here"/><br/>

<asp:Button runat="server" OnClick="btnTest_OnClick" ID="btnTest" Text="Test"/>

        <telerik:RadAjaxManager runat="server" ID="AjaxManager1">
            <AjaxSettings>
                <telerik:AjaxSetting AjaxControlID="btnTest">
                    <UpdatedControls>
                        <telerik:AjaxUpdatedControl ControlID="lblTest" LoadingPanelID="AjaxLoadingPanel1"/>
                    </UpdatedControls>
                </telerik:AjaxSetting>
            </AjaxSettings>
        </telerik:RadAjaxManager>

and in the code behing

 

        protected void btnTest_OnClick(object sender, EventArgs e)
        {
            lblTest.Text = "12324";
        }

No matther how many times I try, the label could not get updated.
I've used fiddler and part of the response is something like below:

31|updatePanel|lblTestPanel|<span id="lblTest">12324</span>|53|updatePanel|AjaxManager1SU|<span id="AjaxManager1" style="display:none;"></span>

Am I missing anything?

I am using an AutoCompleteExtender for a search textbox and the results go far enough down the page to interfere with a RadGrid. It appears that the z-index of the header on the RadGrid is too high as my autocomplete results appear under the header but over the rest of the RadGrid. Any ideas on how to lay my autocomplete results over the RadGrid header?

My site has the need to close a menu if the mouse leaves the window (its very close to the left edge, so its easily left open).

As we have multiple menu's on our page, there is the unlikely possibility that more tha none could be left open, so I really wanted to use a jQuery selector to find all menu controls, and fire its close() method when the mouse leaves the window.

I got to this :

 

$telerik.$(document).mouseleave(

    function () {
        $('.RadMenu').close();
        }
);

 

However, the $('.RadMenu').close(); doesn't work - erroring that close() isn't supported. if I go through the results from $('.RadMenu'), they do seem to be the correct elements being returned (HTMLDiv objects).

Can anyone help?

Thanks,

Andrew

I am dynamically generating a list of columns for a radgrid and everything there is fine the issue that occurs when I'm trying to convert a GridBoundcColumn to a GridDropDownListColumnEditor on the CreateColumnEditor

I was wondering if it was possible to add to add a drop down list, combo box or even a lookup button to the edit template on the radgrid
*Note the datatable is just for testing the columns are coming from a database
