Hello,,

 

I know how to select all checkbox of the grid. In this it selects all the checkbox on all the pages of the grid.

What I want is it should be able to check all the items on that particular page of the grid.

So if I am on 1st page and I hit check all button then it should check all the checkbox on that page. Now when I go to next page and hit check all then it should select all checkbox on second page of grid....so on same way for uncheck all too........................

 

Can any one help me out with this implementation.........

Thanks

Just the other day I needed the same functionality for checkboxes in a GridView so wrote a short Javascript function that is registered as a client script block during the Pre_Render event. In the following,

btnSelectAll and btnClearSelected are references to two LinkButtons
gvExpiredPosts is a reference to the GridView
'cbSelected' is the ID of the CheckBox controls placed in a TemplateColumn of the GridView

Here's the code (Note: remove space between java and script):

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
            
      btnSelectAll.OnClientClick = "java script:return setAllSelected('" & gvExpiredPosts.ClientID & "', true);"
      btnClearSelected.OnClientClick = "java script:return setAllSelected('" & gvExpiredPosts.ClientID & "', false);"
      
      'other code here
End Sub


Protected Sub Page_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PreRender
     Dim sb As New StringBuilder
            
     sb.AppendLine("function setAllSelected(gvCtrlID, selected) {")
     sb.AppendLine("    var gvCtrl = document.getElementById(gvCtrlID);")
     sb.AppendLine("    if (gvCtrl) {")
     sb.AppendLine("         var cbs = gvCtrl.getElementsByTagName('input');")
     sb.AppendLine("         for (var i=0; i < cbs.length; i++) {")
     sb.AppendLine("            var cb = cbs[i];")
     sb.AppendLine("            if (cb.type == 'checkbox' && cb.id.indexOf('cbSelected',0) >= 0) {")
     sb.AppendLine("               cb.checked = selected;")
     sb.AppendLine("            }")
     sb.AppendLine("         }")
     sb.AppendLine("         return false;")
     sb.AppendLine("   }")
     sb.AppendLine("   return true;")
     sb.AppendLine("}")

     If Not Page.ClientScript.IsClientScriptBlockRegistered(Me.GetType, "EPrayer_MngExp") Then
         Page.ClientScript.RegisterClientScriptBlock(Me.GetType, "EPrayer_MngExp", sb.ToString, True)
     End If
 End Sub
