Export To Excel issue on a Master Child Grid data

Hi,

I have implemented a master child rad grid , where the child data for a particular row gets loaded only when user clicks on the uncollapse icon next to the mater data for a particular row.

Now when I am doing an export to excel via ItemCommand, i found that it also tries to load the child data by calling Childgrid_NeedDataSource before doing an export. Is there a way I can stop from doing that and only export the master data?

Note: I am having this issue only when I set IgnorePaging to true. Its works fine with IgnorePaging to false.

Any suggestions

Custom InsertCommand

Hi,

I want to open a radWindow when i click the "Add New Row" Button. I know, i could use a Hyperlink (custom commanditem) - this would be an option if i could use the default style of the Insert Button.

I already stopped the default Insert Event with this code.

protected void gvUser_ItemCommand(object sender, GridCommandEventArgs e)

{

if (e.CommandName == RadGrid.InitInsertCommandName)

{

e.Canceled = true

;

           ... some code ...

}

In the ItemCreaded Event I tried to add a "onclick" event, but this wont work.

protected void gvUser_ItemCreated(object sender, Telerik.Web.UI.GridItemEventArgs e)

{

if (e.Item is GridCommandItem)

{

LinkButton addButton = e.Item.FindControl("InitInsertButton") as LinkButton;

addButton.Attributes["onclick"] = "return ShowInsertForm();";

}

This is my javascript function.

function ShowInsertForm() {

window.radopen("Bearbeiten.aspx?umleitung=-1", "rwBearbeiten");

return false;

}

And this is my radWindowManager

<telerik:RadWindowManager ID="rwmBearbeiten" runat="server" EnableShadow="true">

<Windows>

<telerik:RadWindow ID="rwBearbeiten" runat="server" ShowContentDuringLoad="false"

Width="800px" Height="650px" Title="Bearbeite Umleitungsdaten" Behaviors="Default"

Modal="true" ReloadOnShow="true">

</telerik:RadWindow>

</Windows>

</telerik:RadWindowManager>

I dont have another idea, how i can solve this - i really want to keep the default style of the commanditem - it looks really great.

Best regards,
Raimund

Help Mega Drop Down Menu

Hi, I'm very newbie to this telerik component. I've downloaded the trial products, but I got a problem with mega drop down menu that I tried to create. I've been following the demo isolation steps but got a little confusing with the scenario. If someone could help me with project attachment, it would probably help me so much. Thank you very much.

Cancelled Insert/Update causes AdvancedEditForm to reload without data

Hi,

I am using this server side sample code to prevent appointments from overlapping:

http://demos.telerik.com/aspnet-ajax/scheduler/examples/limitconcurrentappointments/defaultcs.aspx

The problem I am trying to solve is this. If an operation is cancelled using the code above, the advanced edit form redisplays as expected but contains no data. In addition, the Save and Cancel buttons have no text in them, and the title bar of the window is also blank. It's possible to re-enter the data into the blank controls, and save the changes by clicking the blank Save button, but clearly this isn't a situation acceptable to a user.

The control is being hosted in a Sharepoint Visual Web Part, and I have taken measures in the hosting web part to ensure that the ScriptManager provided by Sharepoint is replaced by the RadScriptManager. The FormsCreated event is fired when the form is first shown, but does not execute again for the redisplay of the form following the event cancellation by the server side code.

Has anyone encountered this issue. My suspicion was the Sharepoint ScriptManager, but now that I'm ensuring that the RadScriptManager is in its place have run out of ideas.

Your help is appreciated!

Using DropDownColumn in RadGrid

Hi Folks,

first of all, I'm new to Telerik controls. I'm using a RadGrid to display some data, which contains a DropDown column. The grid is bound to a data table on the page load event. Source of this is a SQL server. Here some Code of my binding:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load

Dim table_competitor_work As DataTable = getSQLData("SELECT competitor, value, units FROM competitor_work")

RadGrid1.DataSource = table_competitor_work

RadGrid1.DataBind()

End Sub

Protected Function getSQLData(ByVal query As String) As DataTable

Dim connString As String = "Data Source=home-sps2010\POWERPIVOT;Initial Catalog=marketsurvey;Integrated Security=SSPI;"

Dim conn As New SqlConnection(connString)

Dim cmd As SqlCommand = New SqlCommand(query, conn)

conn.Open()

Dim dr As SqlDataReader = cmd.ExecuteReader(CommandBehavior.CloseConnection)

Dim dt As New DataTable

dt.Load(dr)

conn.Close()

Return dt

End Function

And here is my markup code:

<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="False"

AutoGenerateDeleteColumn="True" AutoGenerateEditColumn="True" CellSpacing="0"

GridLines="Horizontal" Skin="Telerik" AllowAutomaticDeletes="True"

AllowAutomaticInserts="True" AllowAutomaticUpdates="True">

<MasterTableView CommandItemDisplay="Top" CommandItemSettings-AddNewRecordText="Add new customer">

<CommandItemSettings ExportToPdfText="Export to PDF" />

<RowIndicatorColumn FilterControlAltText="Filter RowIndicator column">

<HeaderStyle Width="20px" />

</RowIndicatorColumn>

<ExpandCollapseColumn FilterControlAltText="Filter ExpandColumn column">

<HeaderStyle Width="20px" />

</ExpandCollapseColumn>

<Columns>

<telerik:GridDropDownColumn EmptyListItemText="Empty"

EmptyListItemValue="Empty" FilterControlAltText="Filter Customer column"

HeaderText="Competitor" UniqueName="Competitor" DataField="competitor">

</telerik:GridDropDownColumn>

<telerik:GridNumericColumn DecimalDigits="2"

FilterControlAltText="Filter Value column" HeaderText="Value 2010"

UniqueName="Value" DataField="value">

</telerik:GridNumericColumn>

<telerik:GridNumericColumn DecimalDigits="0"

FilterControlAltText="Filter Units column" HeaderText="Units 2010"

UniqueName="Units" DataField="units">

</telerik:GridNumericColumn>

</Columns>

<EditFormSettings>

<EditColumn FilterControlAltText="Filter EditCommandColumn column">

</EditColumn>

</EditFormSettings>

</MasterTableView>

<FilterMenu EnableImageSprites="False">

</FilterMenu>

<HeaderContextMenu CssClass="GridContextMenu GridContextMenu_Default">

</HeaderContextMenu>

</telerik:RadGrid>

The strange thing is, the binding an everything works not on the dropdown column. Nothing is displayed and I don't now why. I wanted to bind the dropdown column to a sql datasource and in the insert and edit forms I wanted to diplay other data for the dropdown list. I thought I can do it that way:

DataField="SQLserverField" (bound in code behind at runtime)
DataSourceID="SQLDataSource" (same database, but other table)
ListTextField="SQLDataSourceField"
ListValueField="SQLDataSourceField"

But that isn't working so well. Still there are no value displayed in the grid. But On insert and edit the right values are there.

Do you have an idea?

Thanks and regards,
Mark

Default grouping in SPRadGrid

Is there any workaround for setting GroupBy columns on initial page load? I don't want users to be able to change the grouping, I just want it to group by one or more columns when bound to a SharePoint list.
