Hi Everyone, 

I need some help.  I'm building a radgrid with ascx control like this demo Edit Form Type . However, I made some changes where I'm using Entity Framework to store information back to the database.  I'm using the below code to capture the textbox and dropdownlist value and then passing them into my entity code.  

This is where I need some help.  Instead of capturing the textbox value directly, I want to create a property and apply some validation rule in the properties. Then I want to access these properties to get the values from the aspx.cs file. Instead of  string CostCenterName = (userControl.FindControl("txtCostCenterName") as RadTextBox).Text, I need to access the properties.

Code Behind on the .ascx.cs file
public string CostCenterName
        {
             
            get
            {
                return txtCostCenterName.Text;
            }
             
        }

Code Behind on .aspx.cs file
UserControl userControl = (UserControl)e.Item.FindControl(GridEditFormItem.EditFormUserControlID);
          int CostCenterNo = Int32.Parse((userControl.FindControl("txtCostCenterNo") as RadNumericTextBox).Text);
          string CostCenterName = (userControl.FindControl("txtCostCenterName") as RadTextBox).Text;
          int CostCenterType= Int32.Parse((userControl.FindControl("ddlCostCenterType") as RadDropDownList).SelectedValue);
          string UpdateBy = UserName;
          DateTime UpdateDateTime = DateTime.Now;
 
          var insertNew = new CostCenter
          {
              CostCenterNumber = CostCenterNo,
              CostCenterName = CostCenterName,
              CostCenterTypeID = CostCenterType,
              UpdateBy = UpdateBy,
              UpdateDateTime = UpdateDateTime
          };
          try
          {
              DbContext.AddToCostCenters(insertNew);
              DbContext.SaveChanges();
              SetMessage("Cost Center No " + CostCenterNo + " was added!");
          }

I think I jump the gun here, registering a user control does not work in the sense of editing RadGrid. I would still appreciate any help of accessing a property when I click on the insert or edit button.

Hi Anthony,

I'm not clear about your requirement, i guess you want to access the textbox inside a user control in edit/insert form. You can use the ItemCreated event of the radgrid and access the TextBox, set its properties there.

C#:
void grdSample_ItemCreated(object sender, GridItemEventArgs e)
{
   if (e.Item is GridEditableItem && e.Item.IsInEditMode)
  {
   GridEditableItem editItem = (GridEditableItem)e.Item;
   UserControl MyUserControl = (UserControl)e.Item.FindControl(GridEditFormItem.EditFormUserControlID);
   //Access textbox and set it properties 
   TextBox txtCostCenterNo = (TextBox)MyUserControl.FindControl("txtCostCenterNo");
   txtCostCenterNo.ReadOnly = true;
  }
}

Thanks,
Princy

Hi Princy,

Sorry if my question was not worded  clearly but I want to access a property of the ascx page. Not the element property. For example,

public string UserName
{
     get
            {
              return txtUserName.Text;
             }
}
