Compare Validator with Rad Time Picker

Hi all,
I am using Rad Date Ticker and Rad Time Picker for entering date range. For 2 Rad Date Picker i used one compare validator and also use one compare validator for 2 Rad Time Picker. If i chnage any startime i got error from compare validator even if endtime is greater than starttime. For date comparison i added type as date in compare validator. But how can i configure for radtime picker?
But if i change or just select end time again error is cleared.

<telerik:RadTimePicker ID="radstarttime" runat="server" Width="225px" >

<TimeView CellSpacing="-1" Columns="6" Interval="00:30:00" ></TimeView>

</telerik:RadTimePicker>

<asp:RequiredFieldValidator ID="rfvStartTime" Display="Dynamic" ValidationGroup="EditValidation" SetFocusOnError="true" runat="server" ControlToValidate="radstarttime" ErrorMessage="Start Time is Mandatory!!!" Text="*" ForeColor="Red">

</asp:RequiredFieldValidator>

<telerik:RadTimePicker ID="radendtime" runat="server" Width="225px">

<TimeView CellSpacing="-1" Columns="6" Interval="00:30:00"></TimeView>

</telerik:RadTimePicker>

<asp:RequiredFieldValidator ID="rfvEndTime" Display="Dynamic" ValidationGroup="EditValidation" SetFocusOnError="true" runat="server" ControlToValidate="radendtime" ErrorMessage="End Time is Mandatory!!!" Text="*" ForeColor="Red">

</asp:RequiredFieldValidator>

<asp:CompareValidator ID="crvEndTime" runat="server" ControlToCompare ="radstarttime" ControlToValidate ="radendtime" Operator ="GreaterThanEqual" ErrorMessage ="End Time Must be Greater than Start Time" >

loop through diamically created checkbox column problem - can't find checkbox control on the page

We have a diamically created radgrid with lots checkbox column in it. They all display fine. But I have problem for looping through it and get it's value. It seems can't find the checkbox control on the page. Not sure where I missed.

foreach (Functions function in CurrentUserFunctionList)

{

// Set up the RadGrid's columns

// NOTE: We have to use a custom TemplateColumn, because each checkbox is its own unique control, with its own unique ID.

GridTemplateColumn gtcFunction = new GridTemplateColumn();

gtcFunction.HeaderText = function.Description;

gtcFunction.DataField = function.FunctionId.ToString();

gtcFunction.ReadOnly = false;

gtcFunction.AllowFiltering = false;

// NOTE: The FunctionId gets passed in because it's part of each checkbox control's ID...

gtcFunction.ItemTemplate = new RadGridCheckBoxTemplate(function.FunctionId.ToString());

rgWeb.MasterTableView.Columns.Add(gtcFunction);

// Set up the Data Table's columns

DataColumn thiscolumn = new DataColumn();

thiscolumn.Caption = function.Description;

thiscolumn.ColumnName = function.FunctionId.ToString();

thiscolumn.ReadOnly = false;

thiscolumn.DataType = System.Type.GetType("System.Boolean");

MyDataTable.Columns.Add(thiscolumn);

}

public class RadGridCheckBoxTemplate : System.Web.UI.ITemplate

{

private string colname;

/// <summary>

/// This class sets up a Template with dynamically named CheckBoxes in the RadGrid. cName is the unique identifier for th column,

/// which is added to the ID of each CheckBox control.

/// </summary>

/// <param name="type"></param>

public RadGridCheckBoxTemplate(string cName)

{

this.colname = cName;

}

/// <summary>

/// Create the template

/// </summary>

/// <param name="container"></param>

public void InstantiateIn(System.Web.UI.Control container)

{

CheckBox checkbox = new CheckBox();

//checkbox.AutoPostBack = true;

checkbox.DataBinding += new EventHandler(boolValue_DataBinding);

checkbox.ID = "cbox_" + colname;

checkbox.CheckedChanged += new EventHandler(ToggleRowSelection);

container.Controls.Add(checkbox);

}

void boolValue_DataBinding(object sender, EventArgs e)

{

CheckBox cBox = (CheckBox)sender;

GridDataItem container = (GridDataItem)cBox.NamingContainer;

cBox.Checked = (bool)((DataRowView)container.DataItem)[colname];

}

/// <summary>

/// Check and uncheck

/// </summary>

/// <param name="sender"></param>

/// <param name="e"></param>

void ToggleRowSelection(object sender, EventArgs e)

{

((sender as CheckBox).Parent.Parent as GridItem).Selected = (sender as CheckBox).Checked;

}

I need to loop throug the radgrid to get all the column,

use CheckBox cb = (CheckBox)gdi.FindControl(controlname);
or :

foreach (Control ctrl in Page.Controls)

{

if (ctrl is CheckBox)

{

string a = ctrl.ID;// never comes here to show the control id

}

I can't find any chekbox control on my page, not sure why?

Working with RadGrid and TemplateColumns in ItemCommand

Telerik,

Im trying to get the value of a TemplateColumn item when the ItemCommand event is raised. My TemplateColumn looks like the following:

<telerik:GridTemplateColumn HeaderText="User" UniqueName="User" Reorderable="false" Display="true" SortExpression="User">

<ItemTemplate>

<asp:LinkButton ID="btnButton1" runat="server" ToolTip="Edit this user" CommandName="EditUser" Visible="<%# Master.UserPrefs.HasEditRights %>"><%# Eval("User") %></asp:LinkButton>

<asp:Label ID="lblLabel1" runat="server" Visible="<%#!Master.UserPrefs.HasEditRights %>"><%# Eval("User") %></asp:Label>

</ItemTemplate>

</telerik:GridTemplateColumn>

Basically, the template is built using a boolean value (determining if the current user logged in has EditRights to the record) to either display a LinkButton (to launch a custom edit screen) or to display a Label (if the current user doesn't have the appropriate permission).

In the ItemCommand, I would like to get the value of the data bound to either the Label or the LinkButton. The closest I got to getting the information is by doing something like the following:

protected void gvUsers_ItemCommand(object sender, GridCommandEventArgs e)

{

RadGrid grid = (RadGrid)sender;

switch (e.CommandName.ToUpper())

{

case "MyCommandName":

foreach (GridDataItem item in grid.MasterTableView.Items)

{

string cellContent = ((GridLinkButton)item.Cells[3].Controls[0]).Text

}

		      break;

        }

}

Is this the only way to get the Text value of the GridLinkButton? Can you please provide any other information for retrieving the values associated with a TemplateColumn using the markup in my Template?

Thanks

DatePicker Runtime Error when Date is outside of Min/Max date

I add datepicker to webform
set min date to 1/1/1900
set max date to 12/31/2099
user opens webform on existing record with date of 1/15/2300 (outside min/max date)
a runtime error occurs.

Question(s):
Why the runtime error? this is causing us grief. why doesn't validation just trigger on the datepicker control and display a validation error in the ui?
If i add the datepicker to 100s of forms, do i really have to add try/catch error handling for each when setting the date value of the control? this is a real pain.
