Hi,

I want your help to the following problem.

I have a grid which calls an OnNeedDataSource event to fetch data. The grid columns and data are automatically created based on the list(Of Object) I pass to the grid datasource. The problem I have is that I want to REMOVE and RENAME some columns from the grid but I want to maintain the way the grid works now. How can I rename the column headers of the grid or make them visible false from code behind? From the aspx file I can't do anything because in the ...<MasterTableView><Columns>... tag I don't include any data.

Thanks
George

Filter by unique name - not by Datafield/Displayname does not work

Hello,
I am trying to filter a column in a radgrid with a custom filter template, based on the id´s of the objects and not the display names (in some cases we have entries with the name / display name)

My Code is:

<telerik:GridBoundColumn AllowFiltering="true" AllowSorting="true" DataField="Accountrole.Name"

HeaderText="<%$ Resources:Administration,Role %>" UniqueName="Accountrole.RoleId">

<FilterTemplate>

<telerik:RadComboBox ID="RadComboBoxRole" DataSourceID="RoleDataSource" DataTextField="Name"

DataValueField="RoleId" AppendDataBoundItems="true" SelectedValue='<%# ((GridItem)Container).OwnerTableView.GetColumn("Accountrole.RoleId").CurrentFilterValue %>'

runat="server" OnClientSelectedIndexChanged="RoleIndexChanged">

<Items>

<telerik:RadComboBoxItem Text="<%$ Resources:Basic,All %>" />

</Items>

</telerik:RadComboBox>

<telerik:RadScriptBlock ID="RadScriptBlock1" runat="server">

<script type="text/javascript">

function RoleIndexChanged(sender, args) {

var tableView = $find("<%# ((GridItem)Container).OwnerTableView.ClientID %>");

tableView.filter("Accountrole.RoleId", args.get_item().get_value(), "EqualTo");

}

</script>

</telerik:RadScriptBlock>

</FilterTemplate>

</telerik:GridBoundColumn>

Unfortunately the filtering does not work because my entity data source get athe following filterexpression from the grid (seen in debug mode):
RadGrid1.MasterTableView.FilterExpression = "(it.Accountrole.Name = \"1\")"
but it should be:
RadGrid1.MasterTableView.FilterExpression = "(it.Accountrole.RoleId= \"1\")"

How can I tell the Grid to generate the correct filter expression?

Thanks in advance!

How can I access to a control exists in a EditItemTemplate from a custom event handler ?

Hi,

I want to set a value in a control exists in a GridTemplateColumn, I've read many threads here about it and I figure out that I must use ItemDataBound event instead,
but actually I can't, because I have a control shows a popup and the popup returns a value by a callback in the server,
so how can I deal with this situation?

The code:

protected void MyCustomControl_ItemSelected(string returnedValue)

{

var control = (RadGrid1.EditItems[0] as GridEdittableItem).FindControl("MyCustomTextBox");

if (control != null)

{

control.Text = returnedValue;

}

Thanks in advance.

Setting Selected Value Programically on Multiple RadComboBoxes and getting an ERROR when Submitting

I am trying to click a submit button after loading and pre-populating and pre-selecting a value of two radcomboboxes.

If I try it with this code: (the setting for the second radcombobox is: EnableAutomaticLoadOnDemand="True" )

<tr>

<td colspan="2"> <b> Supervisor Name </b></td>

<td colspan="3">

<asp:HiddenField ID="CRAFT_CODE_Textbox" runat="server" value="H" />

<asp:HiddenField ID="SUPV_ID_TextBox" runat="server" />

<br />

<telerik:RadComboBox ID="wcOfficerName" Runat="server"

DataSourceID="sdsOfficer" DataTextField="FULL_NAME"

DataValueField="SUPV_ID" EnableAutomaticLoadOnDemand="False"

EnableItemCaching="True" EnableLoadOnDemand="False"

EnableVirtualScrolling="False" Filter="StartsWith" ItemsPerRequest="-1"

MarkFirstMatch="False" Width="279px" ShowMoreResultsBox="False"

Skin="Office2007" LoadingMessage="Loading Please Wait..." EmptyMessage="Please Select Supervisor">

</telerik:RadComboBox>

</td>

</tr>

<tr>

<td colspan="2"> <b> Employee Name</b></td>

<td colspan="3">

<asp:HiddenField ID="EMPL_ID_TextBox" runat="server" />

<br />

<telerik:RadComboBox ID="wcEmployeeName" Runat="server"

DataSourceID="sdsEmployees" DataTextField="FULL_NAME"

DataValueField="PERSON_ID" EnableAutomaticLoadOnDemand="True"

EnableItemCaching="True" EnableLoadOnDemand="False"

EnableVirtualScrolling="False" Filter="StartsWith" ItemsPerRequest="-1"

MarkFirstMatch="False" Width="279px" ShowMoreResultsBox="False"

Skin="Office2007" LoadingMessage="Loading Please Wait..." EmptyMessage="Please Select Employee">

</telerik:RadComboBox>

<br />

</td>

</tr>

It works.

However if I change the second radcombobox setting to EnableAutomaticLoadOnDemand="False" then it errors out when I click the "submit" button.

For the error please see attached "error.jpg"

To set the selectedvalue of each rad box I use the following code in the page load event:

Me.wcEmployeeName.SelectedValue = dataset.Tables(0).Rows(0)(4)

Me.wcOfficerName.SelectedValue = dataset.Tables(0).Rows(0)(3)

Please help!

Muli-Row Headers supported by RadGrid?

    
            I currently am using a Repeater (below) and I want to replace it with a RadGrid control.  

            Can I create multi-row headers with a RadGrid control?  

            I have other more complex header that span rows etc., are they supported?
