Fill RadDropDownList in Grid with BatchEdit Mode

Hi,

I have the following grid:

<TELERIK:RADGRID ID="RadGridProductCharacteristics" runat="server" AutoGenerateColumns="false" AllowAutomaticUpdates="true" OnItemUpdated="RadGridProductCharacteristics_ItemUpdated" OnItemDataBound="RadGridProductCharacteristics_ItemDataBound" OnItemCommand="RadGridProductCharacteristics_ItemCommand" OnPreRender="RadGridProductCharacteristics_PreRender">
	<CLIENTSETTINGS AllowGroupExpandCollapse="true" />
	<MASTERTABLEVIEW DataKeyNames="CharacteristicID" GroupLoadMode="Client" CommandItemDisplay="Top" EditMode="Batch">
		<BATCHEDITINGSETTINGS EditType="Cell" />
		<GROUPBYEXPRESSIONS>
			<TELERIK:GRIDGROUPBYEXPRESSION>
				<GROUPBYFIELDS>
					<TELERIK:GRIDGROUPBYFIELD FieldName="ParentCharacteristicName" />
				</GROUPBYFIELDS>
				<SELECTFIELDS>
					<TELERIK:GRIDGROUPBYFIELD FieldName="ParentCharacteristicName" HeaderText="Parent Characteristic" />
				</SELECTFIELDS>
			</TELERIK:GRIDGROUPBYEXPRESSION>
		</GROUPBYEXPRESSIONS>
		<COLUMNS>
			<TELERIK:GRIDBOUNDCOLUMN HeaderText="Characteristic" DataField="CharacteristicName" ReadOnly="true" />
			<TELERIK:GRIDBOUNDCOLUMN UniqueName="CharacteristicValue" HeaderText="Value" DataField="CharacteristicValue" />
			<TELERIK:GRIDTEMPLATECOLUMN HeaderText="Color" UniqueName="CharacteristicColor" DataField="CharacteristicColor">
				<ITEMTEMPLATE>
					<%# Eval("CharacteristicColor") %>
				</ITEMTEMPLATE>
				<EDITITEMTEMPLATE>
					<TELERIK:RADDROPDOWNLIST runat="server" ID="RadDropDownListColor" />
				</EDITITEMTEMPLATE>
			</TELERIK:GRIDTEMPLATECOLUMN>
			<TELERIK:GRIDBUTTONCOLUMN UniqueName="ImageButtonDelete" HeaderText="Action" ButtonType="ImageButton" ImageUrl="~/Resources/Images/icon_delete.png" CommandName="Delete" />
		</COLUMNS>
	</MASTERTABLEVIEW>
</TELERIK:RADGRID>

I would like to fill the RadDropDownListColor so it is filled when the user clicks the cell to edit the value.

I checked this article: Column Editors and from there I derived the following code:

protected void RadGridProductCharacteristics_PreRender(object sender, EventArgs e)
{
	GridTableView masterTable = (sender as RadGrid).MasterTableView;
	RadDropDownList radDropDownListColor = masterTable.GetBatchColumnEditor("CharacteristicColor") as RadDropDownList;

	radDropDownListColor.DataSource = DBCom.GetHTMLColors();
	radDropDownListColor.DataTextField = "HTMLColorName";
	radDropDownListColor.DataValueField = "HTMLColorCode";
	radDropDownListColor.DataBind();
	radDropDownListColor.Items.Insert(0, new DropDownListItem("", "0"));
}

But still the variable radDropDownListColor is null.

What am I doing wrong?

How to prevent UI elements from improperly rendering on page load on mobile website?

I am creating a mobile website using radcomboboxes inside of update controls that are set to autopostback = true. All of the controls work except on the page's initial load the UI elements are enlarged and look more like buttons. They are still able to be selected and after the controls postback the elements still do not go back to a normal size. Only after a postback from another control do the UI elements shrink down to a normal size.

I have tested the radcombobox with checkboxes enabled outside of the update panel and this behavior does not change. I have a master page that contains jQuery files located in the header, and when I remove one of the js files, the problem disappears with the UI elements disappearing. Can anyone help me figure out what is preventing the UI elements from rendering properly?

On Load:

After postback:

RadComboBox don't dropdown on Click in Text when in a RadWindow modal container

I have placed a RadComboBox inside a RadWindow I am using as a modal popup to capture some info. The RadComboBox is dynamically databound to a datatable result set and I can confirm that the data is loaded into the RadComboBox by clicking Up/Down arrows, I can see the other entries. However, clicking on the dropdown button, the dropbox will not expand. I have also tried the basic RadDropDownList with the same result.

I then tried an asp:DropDownList and it work's correctly.

If I place the RadComboxBox outside of the RadWindow, it works. There are no javascript errors on the page.

Can anyone help?

<telerik:RadWindow ID="Results_popup" runat="server" Title="Import Results" VisibleTitlebar="true" VisibleStatusbar="false" VisibleOnPageLoad="false"
    Modal="true" Width="900px" height="600px" DestroyOnClose="True" KeepInScreenBounds="true" OnClientClose="ClosePopUpWindow_Replace"
    Behaviors="Close, Move, Resize">
    <ContentTemplate>
        <div id="inner-container" class="window-container">
            <asp:UpdatePanel ID="UpdatepanelListEdit" runat="server" UpdateMode="Conditional" RenderMode="Block" Visible="false">
                <ContentTemplate>
                        <div class="row">
                            <telerik:RadComboBox RenderMode="Lightweight" ID="drpListStatus" runat="server" Width="200" Label="Status:" />
                            <telerik:RadDropDownList ID="drpListStatusX" runat="server" />
                            <asp:DropDownList ID ="drpListStatusTmp" runat="server" CssClass="dropdown" />
                        </div>

RadDropDownList Data being altered before bind?

i'm lost on this. I have a rad dropdown list that if I run through debugger and step through, it binds correctly showing years 2017-2022 from a SQL Query. This is the weird part... If I build and run it on the dev server, somehow the years are being bound -1, displaying 2016-2021. I have done a find for every reference to the dropdown and it is only accessed on two occasions - page load and on change, what. in. the. world. is going on with this thing?

i've tried clearing the DDL, creating a new instance of DataSet, iterated through the returned dataset and bound each row individually, and everything else just short of clapping 3 times & doing the hokey pokey.

DDLyear.Items.Clear();
string yrSQL = "select year4 as TEXT, year4 as VALUE from " + INSERT_TABLE_NAME_HERE + " group by year4 ORDER BY YEAR4 DESC";
DataSet ds = new DataSet();
ds = GetDataSet(yrSQL);
DDLyear.DataSource = ds;
DDLyear.DataBind();

Attached screenshots show the results running in debug and on dev server.

How to get the name of failing RadComboBox sourced in declarative programmatic way

Hi,

I have a project whot lots of aspx pages, each one containing lot's of RadComboBoxes which are populated with declarative Data Sources :for each RadCombBox I define a certaing Object Data Source so to populate each RadComboBox whith proper items

let's consider a page in which I define:

1) the RadComboBox with rcbCDRATEINDEX ID, which items are coming from odsTBRCFINPRICE_CDRATEINDEX Object Data Source calling the select method GetDataByCDCOMPANY
2) the RadComboBox with rcbCDrcbTPPLAN ID, which items are coming from odsTBRCFINPRICE_TPPLAN Object Data Source calling call the select method GetDataByCDCOMPANY_CUSTTYPE
3) the RadComboBox with rcbPER_SUG ID, which items are coming from odsTBRCFINPRICE_PER_SUG Object Data Source calling call the select method GetDataByCDCOMPANY_PER_SUG

<telerik:RadComboBox ID="rcbCDRATEINDEX" runat="server" DataSourceID="odsTBRCFINPRICE_CDRATEINDEX"
DataTextField="DSRATEINDEX" DataValueField="CDRATEINDEX" Width="100%" OnClientSelectedIndexChanged="ClientRcbCDRATEINDEX_SelectedIndexChanged" />
<asp:ObjectDataSource ID="odsTBRCFINPRICE_CDRATEINDEX" runat="server"
OldValuesParameterFormatString="original_{0}" SelectMethod="GetDataByCDCOMPANY"
TypeName="DataAccessComponent.dsFinancialMarketAndRateTableAdapters.TCRATEINDEXTableAdapter">
<SelectParameters>
<asp:ControlParameter ControlID="hCDCOMPANY" DefaultValue="''" Name="CDCOMPANY" PropertyName="Value" Type="String" />
</SelectParameters>
</asp:ObjectDataSource>
...

...
<telerik:RadComboBox ID="rcbTPPLAN" runat="server" DataSourceID="odsTBRCFINPRICE_TPPLAN"
DataTextField="DSCUSTOM" DataValueField="CUSTKEY" Width="100%" OnClientSelectedIndexChanged="ClientRcbTPPLAN_OnSelectedIndexChanged" />
<asp:ObjectDataSource ID="odsTBRCFINPRICE_TPPLAN" runat="server"
OldValuesParameterFormatString="original_{0}" SelectMethod="GetDataByCDCOMPANY_CUSTTYPE"
TypeName="DataAccessComponent.dsOtherTableAdapters.TBCUSTOMTableAdapter">
<SelectParameters>
<asp:ControlParameter ControlID="hCDCOMPANY" DefaultValue="''" Name="CDCOMPANY" PropertyName="Value" Type="String" />
<asp:Parameter DefaultValue="DEPR_PLAN" Name="CUSTTYPE" Type="String" />
</SelectParameters>
</asp:ObjectDataSource>
...

...
<telerik:RadComboBox ID="rcbPER_SUG" runat="server" DataSourceID="odsTBRCFINPRICE_PER_SUG"
DataTextField="DSCUSTOM" DataValueField="CUSTKEY" Width="100%" />
<asp:ObjectDataSource ID="odsTBRCFINPRICE_PER_SUG" runat="server"
OldValuesParameterFormatString="original_{0}" SelectMethod="GetDataByCDCOMPANY_PER_SUG"
TypeName="DataAccessComponent.dsOtherTableAdapters.TBCUSTOMTableAdapter">

<asp:Parameter DefaultValue="PER_SUG" Name="CUSTTYPE" Type="String" />
</SelectParameters>
</asp:ObjectDataSource>

Now let's suppose that a developer's bug causes that the method GetDataByCDCOMPANY_CUSTTYPE produces no data.

Then an exception of this kind is generated:

Exception Message: 'System.Web.HttpUnhandledException'.

This kind of exception is a generic one, because it states that a component Telerik.Web.UI.RadComboBox of the page, fails during it's Data Binding performing.

This exception don't tell me that THE RadComboBox rcbTPPLAN, which use declaratively the method GetDataByCDCOMPANY_CUSTTYPE, fails.

So every time that happens an exception like that above mentioned, we're in the panic, struggling to understand which declaratively sourced Rad Combo Box produce the error.

Is there a way to understand the rad combo box id that produced the exception?
