I implemented MultiColumn Headers on my radGrid, very cool!

Exporting to Excel however is not doing so great. It only takes the lowest level headers, but with column span of the top level, causing all sorts of wierdness....

Any suggestions on how to export the grid as is, meaning all levels of the headers and data?

conditional Alternating Item Style

hi,

just like james in this thread, I need to mark certain rows according to a condition.
every time the user opens and watch an idea, the row of the watched idea should be in lightblue.
that for itself works great.
My problem is, that when I click a row it gets lightblue, but then- when I click another row, the previous row change color to white.
How can I keep the condition working for alternating item style too?

that my code :

<telerik:RadGrid Skin="innovation" EnableEmbeddedSkins="false" ID="RadGrid1"

dir="rtl" HeaderStyle-ForeColor="White" AllowFilteringByColumn="True"

AllowSorting="True" AllowPaging="True" BorderColor="#74ABAE" BackColor="White"

BorderWidth="2px" runat="server" HeaderStyle-Font-Size="Small" ItemStyle-Font-Size="Small"

AlternatingItemStyle-Font-Size="Small" ItemStyle-BackColor="White" ItemStyle-ForeColor="Black"

PageSize="7" AutoGenerateColumns="False" PagerStyle-Font-Size="Small"

Protected Sub RadGrid1_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles RadGrid1.ItemDataBound

Try

If TypeOf e.Item Is GridDataItem Then

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

Dim idea_code As Integer = CInt(item("IDEA_CODE").Text)

If (StoredProcedures.Is_Watched_Idea(idea_code, userID) = True) Then 'if the ideas was watched then

item.BackColor = Drawing.Color.LightBlue 'color the row

End If

….

End sub

by the way- I tried disable alternating row in client settings but all I got is a transparent back color for the alternative rows.

can anyone help with that?
kind regards, Dana

RadGrid / GridTableView ItemCommand not firing

I have a RadGrid that contains a GridTableView in the DetailTables, as such:

<telerik:RadGrid ID="RelatedProductsGrid" runat="server" Width="95%" ShowStatusBar="true"

AutoGenerateColumns="False" PageSize="20" AllowSorting="False" AllowMultiRowSelection="False"

AllowPaging="True">

<pagerstyle mode="NextPrevAndNumeric"></pagerstyle>

<mastertableview width="100%" datakeynames="PartId" allowmulticolumnsorting="False">

<DetailTables>

<telerik:GridTableView DataKeyNames="PartId" Name="RelatedProducts" Width="100%">

<Columns>

...

<telerik:GridTemplateColumn HeaderStyle-HorizontalAlign="Right" ItemStyle-HorizontalAlign="Right">

<ItemTemplate>

<telerik:RadButton ID="RemoveRelatedProductButton" runat="server" CommandName="Delete">

</telerik:RadButton>

</ItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

</telerik:GridTableView>

</DetailTables>

So, the above button, "RemoveRelatedProductButton" shows up allright, but whenever I press it - nothing happens.

I have this in the code behind:

_relatedProductsGrid = FindControl("RelatedProductsGrid") as RadGrid;
_relatedProductsGrid.ItemCommand += RelatedProductsGrid_ItemCommand;

And finally:

protected void RelatedProductsGrid_ItemCommand(object source, Telerik.Web.UI.GridCommandEventArgs e)
{
if (e.CommandName == "Delete")

etc.

However, this method never fires. What do I need to do?

"Requested registry access is not allowed"?

When I upgrade an existing project to a newer version the Upgrade Wizard Log shows success but I get this error:

https://drive.google.com/open?id=1l1KqfmqRnsCgWJ5O5LeBDCH_fpjDoiRr

Also if I bring up the Launch Toolbox Configurator and then click "Finish" button, I get the same error.

I do NOT run VS 2015 "As Admin" for many reason I don't want to get into, so please don't suggest that ;)

Cheers, Rob.

which telerik control acts like an ASP.NET Datalist?

Hi All

I have an ASP.NET datalist which is displaying data in the form of a repeated list.

I have set the RepeatColumns to 6, so that I have the data displayed repeatedly in 6 columns.

Is there a telerik control that can do this, ie repeat the data in columns?

I tried using a RadGrid but cannot get the data to display in 6 columns.

Any help is very much appreciated.

Thanks

Johann

[Solved] CommandItemSettings AddNewRecordButton and CSS

There are only two settings I can set from the aspx file for the AddNewRecord Button of a radgrid (when it's visible).

CommandItemSettings-AddNewRecordText
CommandItemSettings-AddNewRecordImageUrl

...but this is not enough.

Is there a way to control the appearance of the add button with css?

I can do this for the edit button (for example) of each row by:

Dim ImgBtn As ImageButton = DirectCast(e.Item.FindControl("EditCommandColumn"), ImageButton)
ImgBtn.CssClass = "editbutton"

...in the itemCreated event.

Thanks

[Solved] TreeList delete confirmation

Hi,

I can successfully delete rows from my TreeList but I need to show the user a popup confirmation box first. I have searched extensively for a solution and cannot find anything.

My code for removing a row is listed below:

protected void OnSettingsTreeListDeleteCommand(object sender, TreeListCommandEventArgs e)

{

TreeListDataItem treeListDataItem = e.Item as TreeListDataItem;

TableRow tableRow = e.Item as TableRow;

if (treeListDataItem != null && tableRow != null)

{

string name = tableRow.Cells[3].Text;

string id = treeListDataItem.GetDataKeyValue("Id").ToString();

SettingsTreeListDataTable.Rows.RemoveAt(Convert.ToInt32(id));

PropertyType.GetPropertyType(typeof(Brand)).RemoveSetting(name);

}

I guess I need some kind of java script popup.

Thanks

SurfRat.
