Why is this column converting the filter value to upper case?

I have created a custom grid column, so that I can create my own filter control (a combo box).

This was working well, but at some point it stopped working.

After a day of debugging, I've honed in on the problem.

In my case, the field name is "CompanyName", and the user has set the filter value to be "Acme".

The function GridColumn.EvaluateFilterExpression is returning the string:

CompanyName = "Acme".ToUpper()

Obviously, I don't want to convert the string to upper case.

I've overridden the function "EvaluateFilterExpression" as so:

public override string EvaluateFilterExpression(GridFilteringItem filteringItem)

{

System.Diagnostics.Debug.WriteLine(string.Format("--- GridHyperlinkColumnWithComboFilter.EvaluateFilterExpression({0})", filteringItem));

var rv = base.EvaluateFilterExpression(filteringItem);

System.Diagnostics.Debug.WriteLine(string.Format("--- GridHyperlinkColumnWithComboFilter.EvaluateFilterExpression({0}) returning \"{1}\"", filteringItem, rv));

return rv;

}

And the debug output is:

--- GridHyperlinkColumnWithComboFilter.EvaluateFilterExpression(Telerik.Web.UI.GridFilteringItem)
--- GridHyperlinkColumnWithComboFilter.GetCurrentFilterValueFromControl - returning "Acme"
--- GridHyperlinkColumnWithComboFilter.EvaluateFilterExpression(Telerik.Web.UI.GridFilteringItem) returning "CompanyName = "Acme".ToUpper()"

I've scoured all of the properties of the grid and the column, but can't figure out why "ToUpper" is appearing in the filtering expression.

What would be causing the method "Telerik.Web.UI.GridColumn.EvaluateFilterExpression" to think I want to convert my filter value to upper case?

AllowCustomPaging and CheckBoxList

Hi ALL,

I do have a RadGrid with AllowCustomPaging and a CheckBoxList populated on ItemDataBound when user edits a record.

When user clicks on Update button, NeedDataSource and ItemDataBound events are firing again, so I lose that CheckBoxList selection.

Do you guys have any suggestions?

Thanks,

Grid

Dynamically added User Control utilizing RadInputManager Validation locks up Postback

I have a wizard, Regular ASP.NET for a custom sign up process as the Membership version did not fit the bill. One of the last steps includes a process to register several contacts to associate with the primary account. I wrote a User Control with basic fields for gather Name, Address, City and regular drop down for the State which utilizes a RequiredFieldValidator. This user control utilizes the RadInputManager for controlling the validation.

Here is the User Control markup:

<asp:Panel ID="pnlClient" runat="server">

<asp:TextBox ID="tbClientName" runat="server"></asp:TextBox>

<span class="width500">

<asp:TextBox ID="tbAddress1" runat="server"></asp:TextBox>

<br />

<span class="width250">

<asp:TextBox ID="tbAddress2" runat="server"></asp:TextBox>

<br />

<span class="width250">

<asp:TextBox ID="tbCity" runat="server"></asp:TextBox>

<br />

<asp:DropDownList ID="ddlState" runat="server" DataSourceID="EntityDS_StateProvince"

DataTextField="Name" DataValueField="Id" AppendDataBoundItems="true">

<asp:ListItem Text="[Resident State]" Value="ZZ"></asp:ListItem>

</asp:DropDownList>

<asp:RequiredFieldValidator ID="rfvStateProvince" runat="server" EnableViewState="true" EnableClientScript="true"

ControlToValidate="ddlState" Display="Static"

Enabled="true" ErrorMessage="Valid State is required." InitialValue="ZZ" />

<br />

<span class="width125">

<asp:TextBox ID="tbZip" runat="server"></asp:TextBox>

<span class="width300">

<asp:TextBox ID="tbLetterName" runat="server"></asp:TextBox>

<br />

<span class="width500">

<asp:TextBox ID="tbEmail" runat="server">

</asp:TextBox>

<telerik:RadInputManager ID="rimClient" runat="server">

<telerik:TextBoxSetting BehaviorID="tbbClientName" EmptyMessage="Name" ErrorMessage="Name required."

Validation-IsRequired="true">

<TargetControls>

<telerik:TargetInput ControlID="tbClientName" />

</TargetControls>

</telerik:TextBoxSetting>

<telerik:TextBoxSetting BehaviorID="tbbAddress1" EmptyMessage="Address 1" ErrorMessage="Address is required."

Validation-IsRequired="true">

<TargetControls>

<telerik:TargetInput ControlID="tbAddress1" />

</TargetControls>

</telerik:TextBoxSetting>

<telerik:TextBoxSetting BehaviorID="tbbAddress2" EmptyMessage="Address 2" Validation-IsRequired="false">

<TargetControls>

<telerik:TargetInput ControlID="tbAddress2" />

</TargetControls>

</telerik:TextBoxSetting>

<telerik:TextBoxSetting BehaviorID="tbbCity" EmptyMessage="City" ErrorMessage="City is required"

Validation-IsRequired="true">

<TargetControls>

<telerik:TargetInput ControlID="tbCity" />

</TargetControls>

</telerik:TextBoxSetting>

<telerik:TextBoxSetting BehaviorID="tbbZip" EmptyMessage="Zip" ErrorMessage="Zip is required"

Validation-IsRequired="true">

<TargetControls>

<telerik:TargetInput ControlID="tbZip" />

</TargetControls>

</telerik:TextBoxSetting>

<telerik:TextBoxSetting BehaviorID="tbbContactName" EmptyMessage="Contact Client"

ErrorMessage="Contact Client required" Validation-IsRequired="true">

<TargetControls>

<telerik:TargetInput ControlID="tbLetterName" />

</TargetControls>

</telerik:TextBoxSetting>

<telerik:RegExpTextBoxSetting BehaviorID="tbbEmail" EmptyMessage="Email" ValidationExpression="^\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*$"

ErrorMessage="Invalid Email" Validation-IsRequired="true">

<TargetControls>

<telerik:TargetInput ControlID="tbEmail" />

</TargetControls>

</telerik:RegExpTextBoxSetting>

</telerik:RadInputManager>

<asp:EntityDataSource ID="EntityDS_State" runat="server" ConnectionString="name=LUEntities"

DefaultContainerName="LUEntities" EnableFlattening="False" EntitySetName="StateProvinces"

Where="s.ID != 'ZZ'">

</asp:EntityDataSource>

</asp:Panel>

Step 1 of the wizard uses this control and works fine since only 1 instance of the user control is used. Validation occurs as it should.
Step 2 has an optional step to gather up a contact's beneficiary information. It is optional in the sense that some users choose to set it up later or can choose from a list of supplied Trust Attorneys. if they opt in then I enabled the User control and its subsequent validations. This works fine too.
Step 3 has an optional step to gather secondary beneficiaries information. This is where I am scratching my head. (See Markup)

Somewhere along the line one (or more) of these is failing/doing something unintentional. During Page Load I disable all of the radpanelitems featuring this User Control (ClientUC). I also parse the controls and disabled the RadInputManager as well as the RequiredFieldValidator within them.

<asp:WizardStep ID="Step_SecondBen" StepType="Step" Title="Secondary Beneficiaries">

<telerik:RadAjaxPanel ID="rapBeneficiaries" runat="server" LoadingPanelID="RadAjaxLoadingPanel1">

<telerik:RadButton ID="AddBen" runat="server" Text="Add" OnClick="AddBen_Click" AutoPostBack="true"

CausesValidation="false">

</telerik:RadButton>

<telerik:RadPanelBar runat="server" ID="rpbBenList" ExpandMode="FullExpandedItem"

OnItemClick="rpbBenList_ItemClick" Width="100%" Height="300px" CausesValidation="false">

<Items>

<telerik:RadPanelItem Text="Beneficiary 1" Expanded="true">

<Items>

<telerik:RadPanelItem>

<ItemTemplate>

<uc1:clientuc id="Beneficiary1" runat="server" />

</ItemTemplate>

</telerik:RadPanelItem>

</Items>

</telerik:RadPanelItem>

<telerik:RadPanelItem Text="Beneficiary 2">

<Items>

<telerik:RadPanelItem>

<ItemTemplate>

<uc1:clientuc id="Beneficiary2" runat="server" />

</ItemTemplate>

</telerik:RadPanelItem>

</Items>

</telerik:RadPanelItem>

<telerik:RadPanelItem Text="Beneficiary 3">

<Items>

<telerik:RadPanelItem>

<ItemTemplate>

<uc1:clientuc id="Beneficiary3" runat="server" />

</ItemTemplate>

</telerik:RadPanelItem>

</Items>

</telerik:RadPanelItem>

<telerik:RadPanelItem Text="Beneficiary 4">

<Items>

<telerik:RadPanelItem>

<ItemTemplate>

<uc1:clientuc id="Beneficiary4" runat="server" />

</ItemTemplate>

</telerik:RadPanelItem>

</Items>

</telerik:RadPanelItem>

<telerik:RadPanelItem Text="Beneficiary 4">

<Items>

<telerik:RadPanelItem>

<ItemTemplate>

<uc1:clientuc id="Beneficiary4" runat="server" />

</ItemTemplate>

</telerik:RadPanelItem>

</Items>

</telerik:RadPanelItem>

</Items>

</telerik:RadPanelBar>

</telerik:RadAjaxPanel>

</asp:WizardStep>

The Result I get is that I am unable to navigate forward even if i add (basically enable the user control) 0 beneficiaries. The Next button does not postback. I have added to the user control client side "OnError" functions to the RadInputManager however all 5 RIMs never hit the event (not sure why). I need a method that will tell me which validator is locking up the postback and how to properly address it. I can however postback using the previous button.

What am I missing?

OnCommand fired on Enter key press in outside control

I have textbox that directly has nothing to do with radgrid on the same page.
Textbox has this:

$('#" + filterControl.ClientID + @"').live('keydown', function(event) {

if (event.keyCode && event.keyCode == '13') {

return jsApplyFilterAction" + ParameterSetHolder.Group + @"();

}

else {

return true;

}

});

jsApplyFilterAction**** - method, that calls webservice for filling the grid and making some other things.

For some strange reason when I press Enter being inside this textbox, after executing mentioned method, jsApplyFilterAction, that is ok,

_OnCommand grid event is fired! And command name there is 'Sort'!

As a result, I get unpredictable results and double call of webservice.

I tried to disable _OnCommand event firing with different grid properties, but vain.

How to get rid of this OnCommand triggering and why, after all, it's triggered?

UPDATE: it happens in Firefox, not in IE(9). Chrome is also ok.
