some questions about template textbox in radgrid hierachically

[samaneh]

hi all
I have 3level Hierarchical radgrid in my page.
I  use a template column in it that have RadNumericTextBox and it has TextChanged method.

I have some questions and need your help please:

1)when user expand a node and type numbers in  RadNumericTextBox ,then collapse this,and then expand this node,text of this textbox was clear.
how can I avoid clearing datas(that users enterd)?

2)
In my RadNumericTextBox user enter number for grade.I want check this grade that wasn't greather than grade of it's parent.

In TextChanged Method,how can I reach the value of field "grade" of parent row of this textbox?

Hello Samaneh,

In order to achieve your first requirement set the HierarchyLoadMode="Client" for MasterTableView.

And the following code snippet shows how to get the parent row in 'OnTextChanged' event of RadNumericTextBox.

C#:

protected void RadNumericTextBox_TextChanged(object sender, EventArgs e)
   {
       RadNumericTextBox textbox = (RadNumericTextBox)sender;
       GridDataItem item = (GridDataItem)textbox.NamingContainer;
       GridTableView tableview = (GridTableView)item.OwnerTableView;
       GridDataItem parentItem = (GridDataItem)tableview.ParentItem;//get parent row
       //can access the grade using parentItem
   }

Hello  Samaneh,

Try the following code to achieve this.

C#:

protected void RadNumericTextBox_TextChanged(object sender, EventArgs e)
    {
        RadNumericTextBox textbox = (RadNumericTextBox)sender;
         GridDataItem item = (GridDataItem)textbox.NamingContainer;
        GridTableView tableview = (GridTableView)item.OwnerTableView;
        foreach (GridDataItem coitem in tableview.Items)//loops through each child row
        {
            RadNumericTextBox cotextbox = (RadNumericTextBox)coitem.FindControl("RadNumericTextBox1"); //accessing TextBox using 'ID'
        }
    }

Thanks,
Princy.
