Issue with DatePicker Filter on RadGrid Ie7

Hi guys, im hoping someone can help me out here. Getting a strange rendering issue with the datepicker control on the grid when trying to set a date filter. Basically the control seems to be positioned permanently over the grid when scrolling horizontally. I've attached a screenshot showing the problem.As you can see the datepicker for the date column 'Period To' seems to be completely detached from its usual position. If I scroll across the datepicker also scrolls, same applies to all other date columns - you can just about see the date of birth column has the same issue

Any suggestions?

PS I had to blank out some of the data in the grid as its sensitive data

[Solved] create onclick event with image

I was following an example I found on the site but for some, and it works up to teh point of finding the link buttons text. I need the linkbuttons command argument or the actual text of the link button becuase this is the parameter I need to send thru the querysting to open that page.

It does not seem to get either method.

Protected Sub myRadGridFin_ItemCreated(sender As Object, e As Telerik.Web.UI.GridItemEventArgs) Handles myRadGridFin.ItemCreated

If TypeOf e.Item Is GridDataItem Then

Dim SendDDn As String

Dim item As GridDataItem = DirectCast(e.Item, GridDataItem)

Dim img As Image = DirectCast(item.FindControl("imgPrint"), Image)

Dim DDN As LinkButton = DirectCast(item.FindControl("lnkAdd"), LinkButton)

SendDDn = DDN.CommandArgument.ToString

"neither works"

SendDDn = DDN.Text.ToString

img.Attributes.Add("onclick", "javascript:window.open('??.aspx?DDN=" + SendDDn.ToString() & "'); return false;")

End If

End Sub

[Solved] make Image dissapear if nothing for linkbutton

So I have a print image as part of my radgrid. What I want to do is hide the image button of there is nothing existing for the linkbutton becuase I hide duplicates of the link button. So where the linkbutton is not there I want to also hide the printer image.

<telerik:RadGrid ID="myRadGridFin" runat="server" Width="100%" BorderWidth="1px" CellPadding="6" GridLines="None" BorderColor="#404040" Skin="Web20">

<MasterTableView AutoGenerateColumns="false" DataKeyNames="intRecId" Name="MasterGrid" BorderColor="#404040" Font-Size="9" Font-Names="Veranda,arial,sans-serif"

HeaderStyle-HorizontalAlign="Center" GridLines="Both" BorderWidth="1px"><AlternatingItemStyle BackColor="#B0C4DE" HorizontalAlign="Center" /><ItemStyle HorizontalAlign="Center" />

<HeaderStyle ForeColor="White" Font-Bold="true" BorderColor="#404040" BorderWidth="1px" />

<Columns>

<telerik:GridButtonColumn CommandName="Delete" Text="Delete" UniqueName="DeleteColumn" ConfirmText="Are you sure you want to delete item from turn-in" />

<telerik:GridTemplateColumn>

<ItemTemplate>

<asp:Image ID="imgPrint" runat="server" ImageUrl="~/Images/Printer.png" style="cursor:pointer" />

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn HeaderText="DDN">

<ItemTemplate>

<asp:LinkButton ID="lnkAdd" runat="server"

Text='<%# bind("strDDN") %>' ToolTip="Click to Add Equipment to Doc Number" CommandName="Add" CommandArgument='<%#Bind ("strDDN") %>'></

asp:LinkButton>

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn HeaderText="CATEGORY">

<ItemTemplate>

<asp:Label ID="lblCategory" runat="server" Text='<%# Bind("strCategory") %>'></asp:Label>

<asp:Label ID="lblCatId" runat="server" Text='<%#bind ("intCategoryId") %>' Visible="false"></asp:Label>

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridBoundColumn DataField="strSN" HeaderText="SN" />

<telerik:GridBoundColumn DataField="Equip" HeaderText="EQUIPMENT" />

<telerik:GridBoundColumn DataField="Location" HeaderText="LOCATION" />

</Columns>

</MasterTableView>

</telerik:RadGrid>

Protected Sub myRadGridFin_ItemDataBound(sender As Object, e As Telerik.Web.UI.GridItemEventArgs) Handles myRadGridFin.ItemDataBound

If (TypeOf e.Item Is GridDataItem) Then

Dim img As Image = e.Item.FindControl("imgPrint")

Dim lnk As LinkButton = e.Item.FindControl("lnkAdd")

If lnk.Text = " " Then

img.Enabled = False

img.Visible = False

End If

End Sub

I also tried using it as an e.item.cell(?).text but this did not work either becuase it sees it as a linkbutton column I believe.

[Solved] AutogenerateColumns causing no data to be displayed

Hello,
I have a RadGrid inside a Webpart. Its a non-visual webpart.
I am binding the grid to a Datasource of List<T>.
Every column is being returned from the datasource so I turned off AutoGenerateColumns to remove the extra columns and control what is painted on the screen.

Now the grid always displays "No records to display"...

The radgrid is created in the CreateChildControls override event:

radGridViewSearch = new RadGrid();

radGridViewSearch.AutoGenerateColumns = false;

radGridViewSearch.AllowPaging = true;

radGridViewSearch.PageSize = 25;

radGridViewSearch.NeedDataSource += new GridNeedDataSourceEventHandler(radGridViewSearch_NeedDataSource);

this.Controls.Add(radGridViewSearch);

I am adding only one column to see if I can remove the possible reasons for the error:

GridBoundColumn colFacilityID = new GridBoundColumn();

colFacilityID.DataField = "Facility";

colFacilityID.HeaderText = "Facility";

radGridViewSearch.Columns.Add(colFacilityID);

And the NeedDataSource event is used:

void radGridViewSearch_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)

{

lionRepository = new LionBCSRepository();

radGridViewSearch.DataSource = lionRepository.BuildMatterDataSet(txtMatterNameSearch.Text.Trim(), txtContractNameSearch.Text.Trim(), txtPhysicianNameSearch.Text.Trim());

}

I can see that 40+ records are returned, but its not binding them - is this some strange page life cycle issue?

Please help

PageViews, UserControls and updating between

Hi all,

I'm hoping someone can help with a problem I'm having concerning tabstrip, pageviews and ajax updates.

I have a MultiPage in place with several tabs, and each tab relates to a PageView that in turn contains UserControls.
I have a RadAjaxManager on the main page containing these tabs, and I'm also using a RadAjaxManagerProxy control on each of the UserControls.
I need to communicate between two of these pageviews and usercontrols but I'm having a problem with a particular piece of functionality.
To make it easier to understand I have a "Garment" tab/UserControl that allows customisation of a garment. As a result of changes to the garment, I'd like to update a second tab/pageview ("Branding"). I currently have this working when an "Update" button is clicked on the garment tab that updates an ajaxed datalist on the branding tab (by calling a public subroutine). It seems to work great.
This is based on using an @ Reference tag on the Garment usercontrol, casting an object to this control and then calling the subroutine.

However, there is a situation where if a certain garment is selected, I'd like to be able to show/hide a placeholder on the Branding tab when a radcombobox selectedindexchanged event is fired. I have a public sub on the Branding usercontrol that DOES get called (tested using ajaxpanel.alert), but the placeholders and other controls contained within it do not update. This is doing my head in! :-)

Can anyone suggest why the datalist in the Branding usercontrol can be updated based on an event on the Garment usercontrol, and that a subroutine IS being called for the placeholder update, but the PH doesn't update?

I hope that makes sense and appreciate any insights you may have.

Cheers
Rich

Cannot Save Rel=Me A Tag Parameter

I am trying to setup Google Author Attribution that requires me to have a link from my blog profile that is on a DotNetNuke site using RadEditor to my Google+ profile. And the link has to include a rel="me" parameter. But for some reason I cannot get the RadEditor to save the rel="me" parameter. When I put it in using HTML view and save it then it isn't there when I go back. I know how to edit the Editor settings in DNN but I don't know what I might change that would allow me to save the parameter.
