I want to combin two data fields into one column and want it to be sortable.

Can it be sortable and how?

 

 

<telerik:GridTemplateColumn DataField='company_id,order_no' DataType="System.Int32"

 

 

 

HeaderText="CompanyOrder" SortExpression='company_id,order_no' UniqueName="companyorder">

 

 

 

<EditItemTemplate>

 

 

 

<asp:TextBox ID="order_noTextBox" runat="server" Text='<%#Bind("company_id") +"-"+Bind("order_no") %>'></asp:TextBox>

 

 

 

</EditItemTemplate>

 

 

 

<ItemTemplate>

 

 

 

<asp:Label ID="order_noLabel" runat="server" Text='<%# Eval("company_id")+ "-"+ Eval("order_no") %>'></asp:Label>

 

 

 

</ItemTemplate>

 

 

 

</telerik:GridTemplateColumn>

Thanks for any advice.

I was evaluating the RadComboBox on a project and found that the value field is not being populated. I have tried both the manual process of adding items (RadComboBox1.Items.Add(new RadComboBoxItem(String, String));) as well as binding it to a traditional record set and setting the DataTextField and DataValueField properties. In both cases only the text is being set.

I have a RadCalendar control that I want to show up in an ItemTemplate of a grid.

The problem is the object I am binding to (web service) returns the date in a string format, so when the bind executes, I get an invalid cast error.

Is there a way to convert the string to a datetime so that the Bind operation can be used within the selectedDate property?

Here is what I want to be able to write


But, I get the invalid cast.   This there another way to do this?

I would like to be able to change one column value to an editable text box with a save/cancel button on click is there any way to do this? See my image for further explanation.

I've been trying to set a style on today's date, but the style isn't applying until I have mouse over the date.

Here is the code i'm using to apply the style:

  <calendar ShowRowHeaders="false">
    <SpecialDays>
      <telerik:RadCalendarDay Repeatable="Today" Date="" IsToday="true">
        <ItemStyle BackColor="#eafd9e" />
      </telerik:RadCalendarDay>
     </SpecialDays>
  </calendar>

I'm using asp.net 2.0 with vs 2005.

My current version of telerik is : 2008.1.512.20 - v2.0.50727

Thank you and have a nice day.

** Disclaimer **
The Telerik product was just purchased by us less than 2 weeks ago and therefore as a Newbie, I may have posted this to the wrong forum, and I may be overlooking an obvious resolution.

** Problem **
Unable to set the font-size of the column headings when exporting a grid to PDF.

** Things Tried **
I have tried many things, including some samples directly from Telerik demos. For example:

    bool isPdfExport = false;

    protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e) {
        if (isPdfExport && e.Item is GridDataItem) {
            /// <ColumnHeadings>
            if (e.Item is GridHeaderItem) {
                GridHeaderItem headerItem = (GridHeaderItem)e.Item;

                headerItem.Style["font-size"] = "6pt";

                foreach (TableCell cell in headerItem.Cells) {
                    cell.Style["font-size"] = "6pt";
                }
            }
            /// </ColumnHeadings>

            /// <ColumnData>
            if (e.Item is GridItem) {
                GridItem gridItem = (GridItem)e.Item;

                gridItem.Style["font-size"] = "6pt";

                foreach (TableCell cell in gridItem.Cells) {
                    cell.Style["font-size"] = "6pt";
                }
            /// </ColumnData>
            }
        } //End if (isPdfExport && e.Item is GridDataItem)
    } //End protected void RadGrid1_ItemCreated()

    protected void btnExport_Click(object sender, EventArgs e) {
        isPdfExport = true;

        this.RadGrid1.Visible = true;
        this.RadGrid1.MasterTableView.ExportToPdf();
    }

Within the above event, the ColumnHeadings section fails to resize the font. However, the ColumnData section *will* successfully resize the font. If I change the ColumnData section from 6pt to 12pt font, the data that appears under the column headings (after exporting to PDF) will be resized according. Change it back to 6pt and re-export, and the data is formatted properly.

When making the same change from 6pt to 12pt (or whatever) in the ColumnHeading section, there is no impact on the headings that appear in the PDF. The font size of the column headings remain unchanged. I have no success using "x-small" or "x-large" either (instead of a point size).

I have tried using similiar code in RadGrid1_ColumnCreated() as well as other grid events, but with no luck. BTW, here is the grid schema if interested:

    <telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="true"
                     GridLines="Both" BorderWidth="0.5" Visible="false" 
                     OnNeedDataSource="RadGrid1_NeedDataSource"
                     OnItemCreated="RadGrid1_ItemCreated"
                     OnDataBound="RadGrid1_DataBound"
                     OnColumnCreated="RadGrid1_ColumnCreated">
        <ClientSettings>
            <Resizing AllowColumnResize="true" />
        </ClientSettings>
        <ExportSettings IgnorePaging="true" OpenInNewWindow="true">
            <Pdf AllowPrinting="true" PaperSize="Legal" PageHeight="8.5in" PageWidth="14in"
                 PageBottomMargin="10mm" PageTopMargin="20mm" PageLeftMargin="8mm" PageRightMargin="8mm" />
        </ExportSettings>
    </telerik:RadGrid>

** Resolution **
Unable to determine. Can someone please provide the proper way to resize Column Headings when exporting a grid to PDF?

Thank you,
Steven

OK after hours of failing code. I created a new project and went step by step through your example on http://www.telerik.com/help/aspnet-ajax/window-getting-started.html and it worked just fine.

What would prevent this from working on a website that I need to look for? The only difference from the example and my project is that I am trying to add this functionality to a user control called ucDocumentAccess.ascx and trying to open a web form called DocComments.aspx. Is there something special I need to do for a UC.

Thanks,
Chuck

Hi,

I am using selectedIndexChanged to select a single row of a RadGrid and in CustomGrid_SelectedIndexChange some code is written (say to populate one or more radgrid), so when  I doubleclick on the row it causes Postback. How can I getrid of the postback.

Is there anyway to get rid of postback? Or any alternate for selectedindexchanged?

Thanks,

I have dropdown list edit template column

<EditFormSettings

 

 

EditFormType="Template">

 

 

 

<FormTemplate>

 

 

 

<table id="Table2" cellspacing="2" cellpadding="1" width="100%" border="0" rules="none"

 

 

 

style="border-collapse: collapse; background: white;">

In itemdatabound, it doesn't hit the

 

if ((e.Item is GridDataItem) && e.Item.IsInEditMode)

 

 

 

here is the code

 

 

 

protected void rd_ItemDataBound(object sender, GridItemEventArgs e)

 

{

// if (e.Item is GridEditableItem && e.Item.IsInEditMode)

 

 

if ((e.Item is GridDataItem) && e.Item.IsInEditMode)

 

{

 

 

GridEditableItem edititem = (GridEditableItem)e.It


What i'm missing here?
