I've created a grid where the last column is defined thusly:

      <telerik:GridTemplateColumn UniqueName="StdHrs" DataField="StdHrs">
        <HeaderTemplate>Std Hrs</HeaderTemplate>
        <ItemTemplate>
          <asp:Label ID="labelStdHrs" runat="server" Width="100%" Text='<%# Bind("StdHrs") %>' />
        </ItemTemplate>            
      </telerik:GridTemplateColumn> 

The Std Hrs on each row = Quantity x Rate

After a little research I determined this approach to update the Std Hrs value when a number is changed in the Quantity (aka Units) TextBox:

          float stdHrs = Tools.Round((float)dataRows[0]["Rate"] * newval, 2);
          dataRows[0]["StdHrs"] = stdHrs;
          GridDataItem item = (GridDataItem)textBox.NamingContainer;
          Label label = (Label)item.FindControl("labelStdHrs");
          label.Text = stdHrs.ToString();


This does work but it seems rather redundant to have to update both the underlying DataTable (that the Grid is bound to) as well as the Label that sits in the row.

Is there, in fact, a more efficient way to do this?

Hi,

I am new to Telerik controls.

How to insert data into the grid client-side on a button click . 

Please provide me a sample project/code as I am new to script also.

1) A Combo with ProductName as text, Productid as value.

2) A textbox to enter the Qty.

3) A button (ADD to Grid)  to insert the data into grid client-side

Hi,

I am facing a problem while trying to insert checkbox control into the cell during the itemdatabound event. The grid is tied to the datatable which is created dynamically.

This is the code:

Protected Sub gvCompareAccessories_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles gvCompareAccessories.ItemDataBound

        If (e.Item.ItemType = Telerik.Web.UI.GridItemType.Item Or e.Item.ItemType = Telerik.Web.UI.GridItemType.Item) Then
            'If TypeOf e.Item Is GridDataItem Then
            Dim dt As GridDataItem = DirectCast(e.Item, GridDataItem)

            'Dim imgbox As System.Web.UI.WebControls.Image = New System.Web.UI.WebControls.Image()

            If (e.Item.RowIndex = 2) Then
                Dim plcholder As PlaceHolder = New PlaceHolder()
                Dim chkbox As CheckBox = New CheckBox()
                For Each cellitem As GridTableCell In e.Item.Cells
                    chkbox.Text = "Remove"
                    plcholder.Controls.Add(chkbox)
                    cellitem.Controls.Add(plcholder)
                   
                Next
            End If

        End If
      
    End Sub

Here in the code i am trying to insert the checkbox into each cell of row index 2. But the checkbox appears only in the last column.

I have a radgrid which includes a customized gridtemplatecolumn.  When I export to Excel, it leaves out the customized column.  Can someone show me how to export the column?  I am attaching my front and backend code and a screenshot.  The column name is "Open Items by Age" and includes three data elements.  Also, it there a way to clean up the column so it does not have the weird lines showing in the table.  I set table border to zero.  Thank in advance!

Hi

I have seen it said that the cookie which saves the state of the open items etc is a 'session' cookie.

Does this really mean that it is stored on the server (and therefore not relevant to the EU cookie law) , or is
it stored on the visitor's hard drive (in which case I will have to get permission from the visitors at least for the first visit)?

For most of my client websites, the PanelBar cookie is the only cookie on the site, so it would be handy if I could
forget about it.

Thanks

I try to open a RadWindow that will show different data by clicking a list of linkbuttons.  These linkbuttons should be created at runtime.
I made that work by the following code example


However, there is a problem. If I have 100 items to loop, there will be 100 RadWindows added to RadWindowManager. And this is not  acceptable. I want to use just one RadWindow and let all linkbuttons call this RadWindow, then pass different data to NavigateUrl . The question is how to pass data to just one RadWindow by different linkbutton?

It will be much easier If there is a server side method, like RadWindow.show() or.open(), which can allow me to open RadWindow in code behind. But seems like the only way to open the RadWindow is using javascript?

 

Good afternoon,


I have a problem with compomente RadWindowManger.
I do not know if it was coincidence, but after my last update version of RadControls p / 2012-2-607, the gif loading of pages seem to be grasping, as if slow, ran quickly before the gif.


Here my code I use to open the pages.

I have a grid

<telerik:RadGrid ID="RadGridFeedings" runat="server" AllowAutomaticInserts="True" AllowAutomaticUpdates="True"  AllowAutomaticDeletes="True" AutoGenerateColumns="false" AllowPaging="True" AllowSorting="True" PageSize="10" skin="Default">
                            <PagerStyle Mode="NumericPages" />
                            <GroupingSettings CaseSensitive="false" />
                            <MasterTableView TableLayout="Fixed" Width="100%" CommandItemDisplay="top" DataKeyNames="FeedID" AutoGenerateColumns="false">
                                <Columns>
                                    <telerik:GridDateTimeColumn HeaderText="Date" DataField="FeedDate" UniqueName="FeedDate"
                                        SortExpression="FeedDate" HeaderStyle-Width="20%" ShowFilterIcon="false" DataFormatString="{0:dd/MM/yyyy}" />
                                    <telerik:GridBoundColumn HeaderText="Type" DataField="FoodType" UniqueName="FoodType"
                                        SortExpression="FoodType" HeaderStyle-Width="23%" ShowFilterIcon="false" />
                                    <telerik:GridBoundColumn HeaderText="Size" DataField="FoodSize" UniqueName="FoodSize"
                                        SortExpression="FoodSize" HeaderStyle-Width="22%" ShowFilterIcon="false" />
                                    <telerik:GridBoundColumn HeaderText="Result" DataField="Result" UniqueName="Result"
                                        SortExpression="Result" HeaderStyle-Width="22%" ShowFilterIcon="false" />
                                    <telerik:GridButtonColumn ConfirmText="Delete this product?" ConfirmDialogType="RadWindow"
                    ConfirmTitle="Delete" ButtonType="ImageButton" CommandName="Delete" Text="Delete"
                    UniqueName="DeleteColumn">
                    <ItemStyle HorizontalAlign="Center"/>
                </telerik:GridButtonColumn>
                                </Columns>                                
                            </MasterTableView>
                        </telerik:RadGrid>

that is being loaded using a datatable via the code behind


How do I get the edit/delete buttons working in this scenario as all the examples use sqldatasources or linqdatasources?

Many thanks
Simon

I am new to programming i facing a situation where i need to delete a column to find the new column count of the radgrid.

 Private Sub btnNext_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnNext.Click

        rgdGridOutput.DataSource = ds.Tables(intTableCount)
        rgdGridOutput.DataBind()
        Dim x As Integer = rgdGridOutput.MasterTableView.Columns.Count
       
        rgdGridOutput.MasterTableView.GetColumn("ServiceOutput_Id").Visible = False
        rgdGridOutput.MasterTableView.GetColumn("ServiceResponse_Id").Visible = False

        Dim y As Integer = rgdGridOutput.MasterTableView.Columns.Count
end Sub
I am getting both x and y values as 0. Actually table has 3 columns.

Thanks,
Ajay

Hi, I'm pulling my hair out because I cannot get any image to actually display in the image editor.  I have verified that the handlers are in the web.config and that the link to the image is valid (in Firebug).  Still nothing.  I'm not sure if it's connected, but opening up an image from RadFileEditor brings up a blank window as well.
