Facing a problem while opening a radwindow dynamically

[Ram]

Hi,

My scenarion is like this, I need to open a radWindow on click of a Imagebutton which is in radGrid dyanamically (server side)

 

for that I written code to open radwindow in ItemCommad event of radGrid

 

my problem here is, when I click first time on a Image in radgrid,the debugger passes through the code, the page refreshes and window is added to controls (here the window doesn't open) and when I click on the same image second time the window opens (because the winow is already added to the controls, here the debugger won't go into the code again )

 

I want to open the window on single mouse click of a image (I want to do this on item command event because I need to pass some value to radwindow on click of a imagebutton), How can I achieve this?

muy code is as follows

protected void rdgSystemGrid_ItemCommand(object source, GridCommandEventArgs e)

 

        {

           

 

                if (e.CommandName == "Comments")

                {

                    Telerik.Web.UI.GridDataItem item = e.Item as Telerik.Web.UI.GridDataItem;

                     

                        ImageButton imgComment = (ImageButton)item["comments"].FindControl("imgComments");

                        ShowWindowPopUp(imgComment                   

                }

           

 

private void ShowWindowPopUp(ImageButton imgComment)//, string systemId)

        {

           

            RadWindow window = new RadWindow();

            window.EnableEmbeddedSkins = false;

            window.Title = "Add Comments";

            window.Skin = "Default";

            window.ShowContentDuringLoad = false;

            window.VisibleStatusbar = false;

            window.ReloadOnShow = true;

            window.Behaviors = WindowBehaviors.Reload | WindowBehaviors.Close | WindowBehaviors.Move;

            window.Modal = true;

            window.Width = Unit.Parse("500px");

            window.Height = Unit.Parse("450px");

            window.OpenerElementID = imgComment.ClientID;

             this.Controls.Add(window);

            window.NavigateUrl = @"~/obt/Dashboard/Comments.aspx";

         

 

        }

 

<telerik:GridTemplateColumn UniqueName="comments" HeaderText="Comments" ItemStyle-Width="200px" >

                    <ItemTemplate>

                        <asp:ImageButton ID="imgComments" CommandName="Comments" runat="server" ImageUrl="/comments.gif "/>

                    </ItemTemplate>

                </telerik:GridTemplateColumn>

Hello Ram,

Try setting VisibleOnPageLoad property of RadWindow to True and see whether that makes any difference.

private void ShowWindowPopUp(ImageButton imgComment)//, string systemId)

{

RadWindow window = new RadWindow();

. . .

window.Height = Unit.Parse("450px");

window.VisibleOnPageLoad = true;

this.form1.Controls.Add(window);

. . .

}

Thanks

Shinu.

I want to open a radwindow when user clicks a button ("Select") in a radgrid.

Is there a complete example available?

I don't understand it very well, but I tried to follow the example here:
http://www.telerik.com/community/forums/aspnet-ajax/window/facing-a-problem-while-opening-a-radwindow-dynamically.aspx

When I try it without using window.OpenerElementID = btnSelect.ClientID
then the window does not open.

When I try these commands
         Dim item As GridDataItem = CType(e.Item, GridDataItem)

            Dim btnSelect As Button = CType(item("Select").FindControl("Select"), Button)

then btnselect is null

Here is the code to open the window:

  Protected Sub RadGrid1_ItemCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles RadGrid1.ItemCommand
        If e.CommandName = "Select" Then
            'http://www.telerik.com/community/forums/aspnet-ajax/window/facing-a-problem-while-opening-a-radwindow-dynamically.aspx
            Dim PersonID As String = e.Item.OwnerTableView.DataKeyValues(e.Item.ItemIndex)("PersonID").ToString
            'If permission_ID = 1 or 2 do NOT display link to scs
            Dim item As GridDataItem = CType(e.Item, GridDataItem)

            Dim btnSelect As Button = CType(item("Select").FindControl("Select"), Button)

            ShowWindowPopUp(btnSelect)
        End If
    End Sub
    Private Sub ShowWindowPopUp(ByVal btnSelect As Button)
        'Private Sub ShowWindowPopUp()
        Dim window As New RadWindow()
        window.EnableEmbeddedSkins = False
        window.Title = "Add Comments"
        window.Skin = "Default"
        window.ShowContentDuringLoad = False
        window.VisibleStatusbar = False
        window.ReloadOnShow = True
        window.Behaviors = WindowBehaviors.Reload Or WindowBehaviors.Close Or WindowBehaviors.Move
        window.Modal = True
        window.Width = Unit.Parse("500px")
        window.Height = Unit.Parse("450px")
        window.OpenerElementID = btnSelect.ClientID
        window.VisibleOnPageLoad = True
        Me.Controls.Add(window)
        window.NavigateUrl = "DisplayPicture.aspx"
    End Sub

Hi John,

The RadWindow should be added either to the form's Controls collection or (recommended) to a standard placeholder control in that form.
Another option is to use the client-side API of the controls and to open the window with JavaScript as shown here.

All the best,

Georgi
Thank you for replying promptly.
I found this example that works well:
