Update Text Box Label On Focus

I have a RadTextBox (txtFirstName) that I want to update the label text when the text box has focus:

<%@ Page Title="" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="Person.aspx.cs" Inherits="IncidentTracking.Person" %>

<%@ Register assembly="Telerik.Web.UI" namespace="Telerik.Web.UI" tagprefix="telerik" %>

<asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" runat="server">

<script type="text/javascript">

function Focus(sender, eventArgs)

{

this.txtFirstName.Label = "First Name";

}

</script>

</asp:Content>

<asp:Content ID="Content2" ContentPlaceHolderID="FeaturedContent" runat="server">

</asp:Content>

<asp:Content ID="Content3" ContentPlaceHolderID="MainContent" runat="server">

<telerik:RadTextBox ID="txtFirstName" Runat="server" EmptyMessage="First Name" LabelWidth="64px" Resize="None" Width="160px" TabIndex="1">

<ClientEvents OnFocus="Focus" />

</telerik:RadTextBox>

</asp:Content>

However, when I run this code I get:

0x800a138f - Microsoft JScript runtime error: Unable to set value of the property 'Label': object is null or undefined

RadGrid - WebUserControl - Insert/Edit not working with Sqldatasource

I have done this before in my other project for previous client but still struggling with it. I have similar code but edit/insert is giving "Cannot insert Null into <fieldName>" error. It works in InPlace but not in webusercontrol. It looks like the value is not getting transferred from WebUserControl form to grid for update. I have attached the code and hope to get someone to point out what am I really missing this time.

Filter Menu design gobbledygook

I always thought it was a pretty poor and lazy design decision to have the rad filter menu contain run-on gobbledygook like "GreaterThanOrEqualTo" displayed to the user. And now looking at the Metro skin, it seems Telerik has taken this to a whole new level of poor design by having all-caps stuff like "GREATERTHANOREQUALTO". Now, I'm sure there are folks out there (likely those who think Visual studio 2012 is beautiful) who believe this is great and represents the evolution of UI design. But for the rest of us who aren't as advanced in the design world, would it be possible to provide a simple way of presenting users with a normal, or better yet "classic", interface which doesn't look like the result of a developer whose keyboard is malfunctioning? Phrases have spaces in them. Its how human language has developed over the course of hundreds of thousands of years. Why change now?

Unique Not Null Not Updating

Hi All!

I have an editable RadGrid with a SQL Server 2008 back end. I can successfully update values except when updating one field that is UNIQUE NOT NULL.

When I insert a new item I can populate this field with no issue.

I have checked the update script in SQL Server Management Studio, and it updated the entry correctly.

Can anyone please advise me?

Thanks,
Mark

DropDownList Commands

I can't figure this out. I have a RadComboBox inside a GridTemplateColumn with Items for commands. When a command is selected from the DropDownList it posts back.

protected void gvTransactionsCommandList_SelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e)

{

RadComboBox myBox = (RadComboBox)sender;

if (myBox != null && !string.IsNullOrEmpty(myBox.SelectedValue.Trim()))

{

GridDataItem item = (GridDataItem)myBox.NamingContainer;

RadGrid grid = (RadPane1.FindControl("gvTransactions") as RadGrid);

gvTransactions.MasterTableView.Items[item.ItemIndex].Selected = true;

(grid.MasterTableView.GetItems(GridItemType.CommandItem)[0] as GridCommandItem).FireCommandEvent(myBox.SelectedValue, string.Empty);

}

This Fires the selected command. Which is processed by this code.

protected void gvTransactions_ItemCommand(object sender, Telerik.Web.UI.GridCommandEventArgs e)

{

switch (e.CommandName)

{

case "InitInsert":

gvTransactions.SetInsertControl("UserControls/TransactionDetails.ascx");

break;

case "RowClick":

gvTransactions.SetUpdateControl("UserControls/TransactionDetails.ascx", e);

break;

case "ViewProcess":

gvTransactions.SetUpdateControl("UserControls/TransactionDetails.ascx", e);

break;

case "PerformInsert":

UserControl userControl = gvTransactions.GetInsertControl(e);

break;

case "PerformUpdate":

DataTable dtOld = StoredProcedure.ReturnData("spPeople_AppointmentManager_Get", "@TransactionID", gvTransactions.GetKeyValue(e));

UserControl userUpdateControl = gvTransactions.GetUpdateControl(e);

gvTransactions.CloseUpdateControl(e);

break;

case "PerformDelete":

StoredProcedure.RunCommand("spPeople_AppointmentManager_Delete", "@AcademicID", gvTransactions.GetKeyValue(e));

gvTransactions.CloseUpdateControl(e);

break;

}

This code is sent here to bind the UserControl appropriate for the selected command.

public static void SetUpdateControl(this RadGrid control, string userControlName, GridCommandEventArgs e)

{

control.MasterTableView.EditFormSettings.EditFormType = GridEditFormType.WebUserControl;

control.MasterTableView.EditFormSettings.UserControlName = userControlName;

control.MasterTableView.EditFormSettings.EditColumn.UniqueName = "EditFormControl";

control.MasterTableView.Items[e.Item.ItemIndex].Edit = true;

control.MasterTableView.Rebind();

}

The Error Comes at this line where it states "invalid index". The e.Item.ItemIndex is -1.

control.MasterTableView.Items[e.Item.ItemIndex].Edit = true;

The issue is when I use the "FireCommandEvent" function, it doesn't set the ItemIndex.

How do I fix this?
