CodeBehind

When you click the button by providing DeptId through textbox it binds the data to Repeater with respect to DeptId. If there are no employees with respect to DeptId then it shows empty Repeater with header and custom message.
  1. protected void btnGetData_Click(object sender, EventArgs e)  
  2. {  
  3.    int DeptId = Convert.ToInt32(txtDeptID.Text.Trim());  
  4.    BindRepeater(DeptId);  
  5. }  
BindRepeater
 
BindRepeater method is used to bind the data to Repeater with respect to DeptId. So we have to pass the DeptId to BindRepeater method. In this example we pass DeptId through TextBox.
  1. private void BindRepeater(int DeptID)   
  2. {  
  3.     try   
  4.     {  
  5.         SqlCommand cmd = new SqlCommand("USP_GetEmployeesByDeptId", con);  
  6.         cmd.CommandType = CommandType.StoredProcedure;  
  7.         cmd.Parameters.AddWithValue("@DeptId", DeptID);  
  8.         SqlDataAdapter adp = new SqlDataAdapter(cmd);  
  9.         DataSet ds = new DataSet();  
  10.         adp.Fill(ds);  
  11.         rptEmpDetails.DataSource = ds;  
  12.         rptEmpDetails.DataBind();  
  13.     }   
  14.     catch (Exception ex)   
  15.     {  
  16.         ////Do your exception handling here  
  17.     }  
  18. }  
If there are no records to bind the Reapeter, then the following Reapeter event will be executed.
  1. protected void rptEmpDetails_ItemDataBound(object sender, RepeaterItemEventArgs e) 
  2. {  
  3.     if (rptEmpDetails.Items.Count < 1)   
  4.     {  
  5.         if (e.Item.ItemType == ListItemType.Footer)   
  6.         {  
  7.             HtmlGenericControl dvNoRec = e.Item.FindControl("dvNoRecords"as HtmlGenericControl;  
  8.             if (dvNoRec != null)   
  9.             {  
  10.                 dvNoRec.Visible = true;  
  11.             }  
  12.         }  
  13.     }  
  14. }  
Output :

When no data is found
