I have a databound grid and am needing to add an additional column that will show a link to a google map for the location designated for the record in each row.

firstly im not sure i am doing this in the correct place, second issue im having (using hard coded parameters) is that the URL is not including these parameter values, the URL just shows the querystring names but none of these has the additional values.

as far as i can see the url format string seems correct and the urlparameters variable is getting the string values set ok, but for some reason they are not replacing the palceholder values in the url.

finally how would i get at the actual datatable values i need once i have this hard coded version working correctly?

heres my code:

Private Sub FillGrid()
        Try

            Dim gc As GridBoundColumn
            Dim glc As GridHyperLinkColumn           

            glc = New GridHyperLinkColumn
            Me.uxGrid.Columns.Add(glc)
            glc.HeaderText = "Map"
            Dim urlparameters As String()           
            urlparameters = New String() {"b12jp", "1234", "32.54545", "-2.2342342"}
            glc.DataNavigateUrlFields = urlparameters
            glc.DataTextFormatString = "{2:D}"
            glc.DataTextFormatString = "{3:D}"
            glc.DataNavigateUrlFormatString = "GoogleMaps.htm?postcode={0}&id={1}&lat={2}&lng={3}"
            glc.UniqueName = ""
            glc.ItemStyle.HorizontalAlign = HorizontalAlign.Center
            glc.Text = "Map"
            glc.HeaderStyle.Width = Unit.Pixel(40)
            glc.HeaderStyle.HorizontalAlign = HorizontalAlign.Center

            For Each col As DataColumn In _myData.Columns

                gc = New GridBoundColumn
                Me.uxGrid.Columns.Add(gc)
                gc.HeaderText = GetCaption(col.ColumnName)
                gc.UniqueName = col.ColumnName
                gc.DataField = col.ColumnName
                gc.Display = True
                gc.HeaderStyle.Width = Unit.Pixel(170)
                gc.ItemStyle.Wrap = True
            Next
           
        Catch ex As Exception
           
        End Try

Hi,

I'm trying to figure out how I can access the controls on a footer row outside the ItemDataBound event.

Objective:
I have a drop down list that has a OnSelected event. When the selection changes it needs to enable/disable controls that are in the footer row.

How can I accomplish this?

Hello Telerik,

There are lots of threads about RadGrid inside RadDocks. I'd like to ask about the reverse - RadDocks inside RadGrid.

Please see below:


Will this work?

I want to populate the grid dynamically with cells of RadDockZones. The reason I want to use RadGrid is I want to be able to easily resize the RadDockZones that are in each cell in a RadGrid.

And when the RadDockZones are created, dynamic RadDocks will be created and placed in any of the created RadDockZones.

Different web controls (textboxes, labels, dropdowns, checkboxes) will be dynamically created in a RadDock.

Will the RadDocks (with its contents) then be able to move to any RadDockZone in the RadGrid?

The size of the RadDockZone will be dependent on the size of the cell in the RadGrid.

Finally, the state of the docks will be saved to a database.

When this state is retrieved from the database, the whole RadGrid with its RadDockZones and its RadDocks will be reconstructed.

Can anyone point me in the right direction? Is there any alternative to using RadGrid and still be able to easily resize cells that have RadDocks in them?

Thanks!

Hi,
I am building an asp.net 2.0 application referencing telerik ajax. The Telerik.Web.UI can not be resolved with following warning,

Warning    8    The primary reference "Telerik.Web.UI" could not be resolved because it has an indirect dependency on the framework assembly "System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" which could not be resolved in the currently targeted framework. ".NETFramework,Version=v2.0". To resolve this problem, either remove the reference "Telerik.Web.UI" or retarget your application to a framework version which contains "System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089".

What should I do? Shall I replace Telerik.Web.UI with older version or something else?

Thanks,

I'm having quite the issue trying to DataBind a bool? value to the Enabled property slider in a GridTemplateColumn of a Grid.
Here is my setup:

This is not working at all. Every item in the slider still remains enabled. Note, while the "Static" bool's can be null, I tried this is with a bool value guaranteed not to be null using Enabled='<%# !(bool)DataBinder.Eval(Container, "DataItem.NormalBool") %>' , and it still doesn't work.
I even tried to do Text='<%# DataBinder.Eval(Container, "DataItem.SomeText") %>' and that didn't show up. Nothing seems to DataBind to the Sliders.

Any advice?
I know I can do all of this through the Grid's itemdatabound, but I'd prefer not to.

Hello,

I'm using a modal dialog which is a RadWindow. The page should present an alert using "radalert" if the user has not saved their work. When the save button is clicked a hidden field is updated "hdnIsModified". When the close button is clicked, the "ClosePage()" function is called which passes an argument to the calling page if the page has been modified. Before the page closes, "onBeforeWindowClose" is called to determine if the alert should be displayed.

The problem is that I'm getting an error message (Cant execute code from a freed script) if the user makes a change to a dropdown list inside the RadAjaxPanel, then clicks "save", then "Cancel". If the user does not change the dropdown list and only clicks "save", then "cancel", it works fine. The dropdown list causes an ajax request since it's inside the radajaxpanel. Any ideas why this could interfere with the RadAlert logic? The "Save" and "Cancel" buttons are not inside the RadAjaxPanel.


RadWindow as Modal:

I just upgraded to the latest version of the RadControls.

I upgraded through the Visual Studio 2010 Telerik menu.
The upgarde took it upon itself to modify the asp code.

Before the upgrade I had code like this...

After the upgrade I had code like this....

Which resulted in lots of errors aboout Unique names not allowed to have spaces.....space I did not put there!!
Why did the upgrade making these changes?
I now have hours of testing and fixing to do!!!!
