Column width in insert/edit mode

Hi.
I have grid where i want to set the column width for each column. I used the headerstyle-width and itemstyle-width for a column. Column width is set correct when the record is not in insert or edit mode. But in insert or edit mode, the column width is changing. I have tried a lot of things, like not have a grid width, set the TableLayout to fixed, different combination of ItemStyle-width and HeaderStyle-width etc. unsuccessfully. So how can i set the column width for insert/edit mode?

the code i am using:

     <telerik:RadGrid ID="RadGrid2" runat="server" DataSourceID="LinqDataSource1" GridLines="None" Width="360px" >
        <MasterTableView AutoGenerateColumns="False" DataKeyNames="EmployeeCompanyNumber" DataSourceID="LinqDataSource1" CommandItemDisplay="Top">
        <CommandItemSettings ExportToPdfText="Export to Pdf"></CommandItemSettings>
        <RowIndicatorColumn><HeaderStyle Width="20px"></HeaderStyle></RowIndicatorColumn>
        <ExpandCollapseColumn><HeaderStyle Width="20px"></HeaderStyle></ExpandCollapseColumn>
        <Columns>
            <telerik:GridNumericColumn ItemStyle-Width="70px" HeaderStyle-Width="80px" FilterControlWidth="90%" DataField="EmployeeCompanyNumber" DataType="System.Int32" HeaderText="Foretaksnr." SortExpression="EmployeeCompanyNumber" UniqueName="EmployeeCompanyNumber">
            </telerik:GridNumericColumn>
            <telerik:GridBoundColumn ItemStyle-Width="190px" HeaderStyle-Width="200px" FilterControlWidth="90%" DataField="Name" HeaderText="Navn" SortExpression="Name" UniqueName="Name" >
            </telerik:GridBoundColumn>
            <telerik:GridEditCommandColumn HeaderStyle-Width="140px" >
            </telerik:GridEditCommandColumn>
            <telerik:GridButtonColumn HeaderStyle-Width="40px" CommandName="Delete">
            </telerik:GridButtonColumn>
        </Columns>
        <EditFormSettings><EditColumn UniqueName="EditCommandColumn1"></EditColumn></EditFormSettings>
        </MasterTableView>
    </telerik:RadGrid>

RadComboBox SelectedValue not updating if selecting item with same text

I have 2 drop downs publisher and heading. If I change the publisher and select a heading with a different value but the same text as the previously selected heading the selected value does not update. But if I select a completely different heading with different text and value it works fine.

Here is my code

function PublisherChanged(combo, eventArqs)
{
    directories.clearSelection()
    headings.clearSelection();
    directories.clearItems();
    headings.clearItems();
    directories.requestItems('',false);
    headings.requestItems('',false);

}

private void PopulateHeadings(string publisherName, string text)
        {

            if (publisherName == "") return;
            DataTable data = GetHeadings(publisherName, text);
            bool noResults = false;
            if (data.Rows.Count == 0)
            {
                noResults = true;
                DataRow row = data.Rows.Add();
                row["value"] = "[No Results]";
                row["Id"] = "0";
            }

            headings.DataSource = GetTopN(data, 15);
            headings.DataTextField = "value";
            headings.DataValueField = "Id";
            headings.DataBind();

            if (noResults)
            {
                headings.Items[0].Enabled = false;
            }

        }

Is the a bug in the control or am I using the control incorrectly?

Open branches clientside

Hello,
I have a RadTreeView that has ExpandMode "TreeNodeExpandMode.ServerSideCallBack". I want to open branches and select a node client-side via Javascript. Is there any example on how to do this?

My target is to refresh the tree after an user right click action on a node. After the right click, I'll do a postback and refresh the tree and reselect the node also opening branches to reach selected node.

RadDateInput - time input validation issue

I am trying to validate the input of a military time. However, it always rejects whatever I enter for the time in the RadDateInput field, but the validation works just fine in a textbox. My test code looks like:

Time:

<telerik:RadDateInput ID="RadDateInput1" runat="server" DateFormat="HH:mm" Width="50" />

<asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server"

ErrorMessage="Invalid Time" ControlToValidate="RadDateInput1" Display="Dynamic"

ValidationExpression="(([01][0-9])|(2[0-3])):[0-5][0-9]" SetFocusOnError="true" />

<br />

Time2:

<asp:TextBox ID="txtTime" runat="server" Width="50" />

<asp:RegularExpressionValidator ID="RegularExpressionValidator2" runat="server"

ErrorMessage="Invalid Time2" ControlToValidate="txtTime" Display="Dynamic"

ValidationExpression="(([01][0-9])|(2[0-3])):[0-5][0-9]" SetFocusOnError="true" />

<br />

<asp:Button ID="btnSubmit" runat="server" CausesValidation="true" Text="Submit" />

Can someone please tell me what I am doing wrong?

Many thanks!

Rad grid results export issue with Ajax

Hello Telerik Team,

I have a requirement for the rad grid to export the results shown in the rad grid dynamically.
I have put this rad grid inside a user control and user control is inside the sharepoint webpart.
I have ajaxified this webpart.
I saw some blogs where it says you cant get the export functionality work if you have ajax.
I have gone through http://www.telerik.com/community/code-library/aspnet-ajax/general/export-radgrid-content-to-excel-word-csv-pdf-with-ajax-enabled.aspx
also..but it would be really helpful if you can send out a sample for ajaxified webpart to use export.
i appreciate your help and support.

Thank you,
Smith

RadGrid inside RadListView problem..

Hi,

I have a RadGrid inside a RadListView (which has a page size of 1), the problem I'm having is that my RadGrid_OnNeedDataSource gets called before my RadListView_OnNeedDataSource. This is problematic because the data I need to populate my RadGrid with is dependent on the
RadListView's new DataKey: ideally in RadGrid_OnNeedDataSource I'd get the NEW DataKeyValue of the RadListView and use that to
call a stored procedure in the database.

If I try to get the RadListView's current item's datakey in RadGrid_OnNeedDataSource I always get the old RadListView item's datakey (i.e. not the one I just selected).

Is there an easy work around for this?

Regards,
-Carlo

scroll horizontal by javascript

Hello,
How can I scroll automatically horizontal by script? I save the RadGrid1.GridDataDiv object status before the RadGrid change:

<script type="text/javascript">

var usersmatrix1scrollArea;

function OnClientScript(args) {

var RadGrid1 = $find("<%= RadGrid1.ClientID %>");

usersmatrix1scrollArea = RadGrid1.GridDataDiv;

}

function GridCreated() {

var RadGrid1 = $find("<%= RadGrid1.ClientID %>");

var scrollArea = RadGrid1.GridDataDiv;

if (usersmatrix1scrollArea != null) {

scrollArea = usersmatrix1scrollArea;

}

</script>

This works only vertically, no horizontal. How can I scroll to the correct Item horizontal?
