根据另一个列表视图中的选择更改列表视图中的选定项目

Question

I have two list views. In the Item command event of the first Listview i am showing the second list view in modal popup using ajaxtoolkit.

protected void lvSelection_ItemCommand(object sender, ListViewCommandEventArgs e)
{
    this.lvPopup.Visible = true;
    this.lvPopup.DataSource = linqdataSource;
    this.lvPopup.DataBind();

    this.mdlPopup.Show();
}

Now in the itemcommand event of the second list view I need to change the content of the selected item in the first listview.

Is it possible to do that?

Answer 1

protected void lvPopup_ItemCommand(object sender, ListViewCommandEventArgs e)
{
    // Set the text of the first list view item to the selected item 
    // of the second list view.
    lstView1.Items[lstView1.SelectedIndex].Text = 
        lstView2.Items[lstView2.SelectedIndex].Text
}

I'd think that if you were to set the CommandName of the selector button in the first ListView to "Select" - from the second list view's ItemCommand event, you should be able to alter either the SelectedItemTemplate or the current item for the selected item in the first list.

protected void lvPopup_ItemCommand(object sender, ListViewCommandEventArgs e)
{

   lvSelection.SelectedItemTemplate = "<div>woohoo!</div>";
   // OR...
   lvSelection.Items[lvSelection.SelectedIndex].SkinID = "SomeNewSkinForExample";


   mdlPopup.Hide();

}

Have you already tried to dynamically generate the items of the List?

On the event code of the 1st list, clear the Items from the 2nd list and populate it with whatever logic suits you.
