Where to set Application wide setting for control?

Hello Folks,

Can anyone tell that if it possible to set some Telerik's components property in ASP.INET Application wide?
For example: I have RadTextBoxes in my Application and when setting their ReadOnly property to false I would rather
want text to appear black than grey.

Where can I chage this kind of settings?

Cheers,

[Solved] How to preserve the state of the rows selected during traversal to other pages

Hi,

I am using a GridClientSelectColumn and have a paging on my grid. I need following things on my grid.

1) Multiple selection client-side

2) If i do select all from the header checkbox on page1, it should also select the rows at all other pages.

3) Deselect should deselect only the single row, not all.

4) If i select a single row on page1, and move on to any other page and now when i come back to page1 the row should persist its state.

I would appreciate any help on this.

Thanks,

Sunil Nahar.

hover on grid -- popup control

hi,

i am a newbie to telerik and ajax, i am trying to show a popup image on move hover for an grid item.
i have found a similar article which says i an use that a itemtemplate and show a popup.

<telerik:GridTemplateColumn UniqueName="TemplateCol" HeaderText="TemplateCol">

<asp:Label id="lblName" runat="server" Text='<%#Eval("ProductName") %>' ></asp:Label>

<asp:Panel ID="popupMenu" runat="server" style="display:none" BackColor="skyblue" >

<asp:Button ID="btnCopy" runat="server"></asp:Button>

</asp:Panel>

<cc1:HoverMenuExtender ID="HoverMenuExtender1" TargetControlID="lblName" runat="server"

PopupControlID="popupMenu" PopupPosition="right" PopDelay="50">

</cc1:HoverMenuExtender>

</ItemTemplate>

</telerik:GridTemplateColumn>

the problem i am facing here is to include the assembly with the tag name "cc1" which has the "HoverMenuExtender" method, i think this is from the ajax control library.

also let me know if it is possible to catch the click event of the button "btnCopy" on the server side ( and) is still need to be able to tell on which cell the click event was raised.
i am stuck with this problem for more than 2 days, so, please help me out.

thank you.

Trying to understand "PageViewCreated" functionality

I'm trying to implement a tabstrip with multipage. My page views are dynamically loaded user controls.

This is basically how the flow works.

I have a RADgrid (named RadGrid1) that contains a number of columns. When you click on a row in the grid, a tab is created that represents the data of that gridrow. To accompish this I use "RadGrid1_ItemCommand" and check for the "RowClick" command. I then get the name of the column I need and use that to name the tab. Here's the C# code to add the new tab and its coressponding page view.

private

void AddTab(string tabName)

{

RadTab tab = new RadTab();

tab.Text = tabName;

RadTabStrip.SelectedIndex = selectedTabIndex;

RadTabStrip.Tabs.Add(tab);

RadPageView pageView = new RadPageView();

pageView.ID = tabName;

RadMultiPage.SelectedIndex = selectedTabIndex;

RadMultiPage.PageViews.Add(pageView);

}

protected

void RadMultiPage_PageViewCreated(object sender, RadMultiPageEventArgs e)

{

string userControlName = "UserControls/VMDetails.ascx";

Control userControl = LoadControl(userControlName, passName, passIP);

userControl.ID = passName +

"_vmdtl";

e.PageView.Controls.Add(userControl);

}

The problem I'm having is that the first two tabs are created fine, but the thrid tab doesn't get created because I get an error on the page indicating the userControl.ID is a dupicate. Trying to debug this issue I noticed that the code doesn't follow the design I think it should follow.

When I click on a row, I would think the first code execution would be in the "RadGrid1_ItemCommand" method to see if the the "RowClick" command is true, however this is not the case. The first execution appears to be the "RadMultiPage_PageViewCreated" method. If you look at the code above, the "passName" value during the execution the third time has a value from the previous tab creation and therefor the userControl.ID is the same.

Why does execution go directly to "RadMultiPage_PageViewCreated'? Any Thoughts?

Thanks!

[Solved] Setting page size on grid using a custom control edit form

I am getting a "The specified value cannot be set on pagesize" error when trying to change the page size with the "NextPrevNumericAndAdvanced" pager while using a custom control edit form.

The line that seems to be causing the error is:
UserControl userControl = (UserControl)e.Item.FindControl(GridEditFormItem.EditFormUserControlID);

In the beginning of the function:

    
            protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)  
        
                    {  
        
                        GridEditableItem editedItem = e.Item as GridEditableItem;  
        
                        UserControl userControl = (UserControl)e.Item.FindControl(GridEditFormItem.EditFormUserControlID);  
        
                        switch (e.CommandName)  
        
                        {  
        
                            case "PerformInsert":

If I Comment this line out ( incuding references to userControl ) setting the page size works.

I am using the newest version 2009.2.906.20

The grid is in a UserControl that I am dynamically adding to the page but I do not have any problems with any other functionality.

Any Ideas on what might be causing this?

Thanks in advance,
Dave
