RadwindowManger problem

[Duy]

Hi,

I have a radwindowmanager problem as implementing with radscheduler.

On the appointment is clicked, the window's visibleonpageload set to be true.  After the things are done and  the window is closed.  However, each time radscheduler is navigated, the window is popped up again.  I am not sure what causes the problem.

I set the ajax update control(radscheduler, radwindowmanager).

Regards,

Duy

Hello Duy,

When we set VisibleOnPageLoad property to True, the window opens for every postbacks. So one suggestion to avoid this behaviour, invoke a postback when closing the window and set the VisibleOnPageLoad property to False for that window.

Hi Duy,

When a RadWindow is declared in  RadWindowManager it preserves its ViewState which was not so in previous versions. This could lead to backwards incompatibility when the VisibleOnPageLoad property is used in this configuration with the idea to show the RadWindow only once. Possible solutions for this case are the following ones:

• Set EnableViewState = "false" for the RadWindowManager
• Reset the VisibleOnPageLoad property to false with code when suitable, depending on the particular scenario
• Show the RadWindow through registering a script from the server instead.

Thanks All,

I approached the solution which Svetlina suggested.  It works with EnableViewState = false and reset VisibleOnPageLoad = false according to the trigged event.  Will try another way which open the window through the script.

cheers,

Hello Duy ,

As far as I understood, my suggestion about setting EnableViewState="false" for the manager worked for your case. If so, I am glad I could help and I recommend to stick to this solution because in my opinion it is better than executing scripts from the server (there are different scenarios when executing the scripts and this might cause more time and effort and also does not have benefits in this case and also you will get better performance by disabling the ViewState).

In case you need further assistance or you have additional questions, do not hesitate to contact us again.

Hi,

Try the following code to open RadWIndow.
C#:

protected void RadGrid2_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridDataItem)
    {
        GridDataItem item = (GridDataItem)e.Item;
        LinkButton btn = (LinkButton)item["edit"].Controls[0];
        btn.Attributes.Add("onclick", "open();return false;");
    }
}

JS:

function open()
{
 var oWnd = radopen("", "RadWindow1");
}

Thanks,
Princy

Hi,

Unfortunately I cannot replicate the issue at my end. Here is the full code that I tried which worked as expected.
aspx:

<telerik:RadGrid ID="RadGrid2" AutoGenerateColumns="false" runat="server" DataSourceID="SqlDataSource2"OnItemDataBound="RadGrid2_ItemDataBound" >
 <MasterTableView  CommandItemDisplay="Top">
  <EditFormSettings EditFormType="Template">
    <FormTemplate>
      <telerik:RadWindow ID="RadWindow1" runat="server" VisibleOnPageLoad="true">
          <ContentTemplate>
             <asp:TextBox ID="TextBox3" runat="server"></asp:TextBox>
          </ContentTemplate>
      </telerik:RadWindow>
    </FormTemplate>
   </EditFormSettings>
    <Columns>
      <telerik:GridEditCommandColumn  UniqueName="edit" ButtonType="LinkButton"></telerik:GridEditCommandColumn>
   </Columns>
 </MasterTableView>
</telerik:RadGrid>

C#:

protected void RadGrid2_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridDataItem)
    {
        GridDataItem item = (GridDataItem)e.Item;
        LinkButton btn = (LinkButton)item["edit"].Controls[0];
        btn.Attributes.Add("onclick", "open();return false;");
    }
}

JS:

function open()
{
 var oWnd = radopen("", "RadWindow1");
}

Thanks,
