Hello,

protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)

{

if (e.CommandName == "YourCommandName")

{

// For Normal mode

GridDataItem item = e.Item as GridDataItem;

TextBox TextBox1 = item.FindControl("TextBox1") as TextBox;

// Access your TextBox Here

// For Edit mode

GridEditableItem eitem = e.Item as GridEditableItem;

TextBox TextBox2 = eitem.FindControl("TextBox2") as TextBox; // From Item Template

TextBox TextBox3 = eitem["ColumnUniqueName"].Controls[0] as TextBox; // From Bound Column

// Access your TextBox Here

}

Thanks,

Hello,

try with below code snippet.

Protected Sub RadGrid1_ItemCommand(sender As Object, e As GridCommandEventArgs)

If e.CommandName = "EditTest" Then

Dim eitem As GridEditableItem = TryCast(e.Item, GridEditableItem)

Dim txtEditIP As RadTextBox = TryCast(eitem.FindControl("txtEditIP"), RadTextBox)

End If

End Sub

'OR

Protected Sub RadGrid1_ItemCommand(sender As Object, e As GridCommandEventArgs)

If e.CommandName = "EditTest" Then

Dim eitem As GridEditFormItem = TryCast(e.Item, GridEditFormItem)

Dim txtEditIP As RadTextBox = TryCast(eitem.FindControl("txtEditIP"), RadTextBox)

End If

End Sub

Thanks,
