Enable / Disable TabStrip Dynamically

[Siva]

Is it possible to Enable or disable the Tab strip based on the Rad Grid Condition. I have Three Tabs and each tab has a RadGrid in it. When a Grid is in Edit mode, I want to Disbale the TasbStrip so that users can not move to a different Tab. Once the users either update or cancel the edit Tab Strip should be enabled back.

I tried setting Tabstrip.enabled to false on Grid Prerender and Item Command, but did not work.

Thanks for your help and advice.

Thanks,
Siva

Hello,

Thank you for contacting Telerik support.

Please, see the following code snippet showing how to disable a RadTabStrip's tab in the RadGrid's PreRender event handler:

protected void RadGrid1_PreRender(object sender, System.EventArgs e)
{
    if (!IsPostBack)
    {
        RadGrid1.MasterTableView.Items[3].Edit = true;
        RadGrid1.Rebind();

        if (RadGrid1.MasterTableView.Items[3].Edit == true)
        {
            var tab = RadTabStrip1.FindTabByText("Documentation");
            tab.Enabled = false;
        }
    }
}

protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)
{
    List<MyClass> list = new List<MyClass>();

    list.Add(new MyClass { Age = 12, Text = "John" });
    list.Add(new MyClass { Age = 32, Text = "Peter" });
    list.Add(new MyClass { Age = 22, Text = "Monica" });
    list.Add(new MyClass { Age = 51, Text = "Kalvin" });
    list.Add(new MyClass { Age = 44, Text = "Terry" });

    RadGrid1.DataSource = list;
}

public class MyClass
{
    public int Age { get; set; }
    public string Text { get; set; }
}

      1. In the code-behind we first populate a RadGrid with sample data using its NeedDataSource event handler.

     2. Then we put its third item into Edit mode in the PreRender event handler. If you want to disable a tab if a particular grid item is in edit mode you can make that check here. In our example we check if the third item is in edit mode and then we disable a tab with a specific text value.

I hope this was useful. Feel free to contact us again if you have more questions.

I have similar events for all grids. In prerender I am trying to disable one tab in the above code.
I tried doing it on all tabs by looping and indivdually which is not working.
What I am trying to achieve here is when an item is in edit mode in any grid I want to disable all the tabs so that users can not perform any action in other grids until the current Edit action completed.
Hope this will give you more understabding of what I am trying to achieve and provide a solution to me.

Hello,

You are not able to update the RadTabStrip due to the fact that the RadGrid is wrapped in the RadAjaxPanel and the RadTabStrip is outside the RadAjaxPanel.

 In this case you can try three approaches you if you want to do that:

1. You can wrap both, the RadTabStrip and the RadGrid in a RadAjaxPanel.
2. You can use RadAjaxManager and set the RadGrid to update the RadTabStrip.
3. Not to use Ajax.

Please, find attached a sample project. I have modified your code slightly and commented out the RadAjaxPanel to make it work (third approach of the above-mentioned options). It demonstrates how a tab in a RadTabStrip is disabled, when an item in RadGrid is in edit mode. Note how we use the OfficeRadGrid_EditCommand event handler to access a tab and change its Enabled property. This event fires when a user clicks on an Edit button in the RadGrid.
