So I am trying to use a radgrid to allow updates to my database, and while the page functions properly, I can't seem to save the data back to the database, any help you can offer would be appreciated greatly. I am new to both C# and asp.

Page Code:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="ValidationEdit.aspx.cs" Inherits="EditPages_ValidationEdit" MasterPageFile="~/EUEMain.master"   %>

Batch Edit RadGrid.EditItems on Save

I have a grid as follows. EditMode=Batch, AllowMultiRowSelection, AllowMultiRowEdit = true

<telerik:RadGrid ID="RadGrid1" runat="server" ClientSettings-Selecting-AllowRowSelect="true" AutoGenerateColumns="False" AllowMultiRowSelection="true" OnNeedDataSource="RadGrid1_NeedDataSource" AllowMultiRowEdit="true">

<MasterTableView EditMode="Batch" DataKeyNames="Discipline_ID" CommandItemDisplay="Top">

<BatchEditingSettings EditType="Row" OpenEditingEvent="DblClick" />

<CommandItemTemplate>

<asp:ImageButton ID="Button_Save" runat="server" ToolTip="Save" ImageUrl="~/dhtmlx/imgs/save.png" Height="20" Width="20" style="padding:5px 0 0 5px;" OnClick="Button_Save_Click" />

</CommandItemTemplate>

<Columns>

<telerik:GridBoundColumn DataField="Discipline_ID" Display="false" UniqueName="Discipline_ID"></telerik:GridBoundColumn>

<telerik:GridClientSelectColumn UniqueName="SelectCheckBox" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center" HeaderStyle-Width="50px"></telerik:GridClientSelectColumn>

<telerik:GridBoundColumn DataField="Name" HeaderText="Name" UniqueName="Name" AllowSorting="true"></telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Description" HeaderText="Description" UniqueName="Description" AllowSorting="true"></telerik:GridBoundColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

When I click the save button in the CommandItemTemplate it fires this event:

protected void Button_Save_Click(object sender, ImageClickEventArgs e)

{

foreach (GridDataItem item in RadGrid1.EditItems)

{

Hashtable newValues = new Hashtable();

item.OwnerTableView.ExtractValuesFromItem(newValues, item);

}

When I try to update the items that have been edited in the grid the RadGrid1.EditItems.Count is always 0.

Why aren't the items that I have edited marked as edited when I try to save them?

Thanks

Ajax not working on first click

I have a number of forms and grids that use RadAjaxManager to setup AJAX settings. This works well after the first click. That first clicks always does a full page refresh which is slow and does not show the RadAjaxLoadingPanel graphic. Is there a way to force the page to register the controls correctly so any click is handled correctly by RadAjaxManager?

The controls are placed in web parts that appear in SharePoint pages.

Excel Export - Specified argument was out of the range of valid values

I am getting this error when a user clicks Export on the radGrid heading:

Specified argument was out of the range of valid values.
Parameter name: index

[ArgumentOutOfRangeException: Specified argument was out of the range of valid values.
Parameter name: index]
System.Web.UI.ControlCollection.get_Item(Int32 index) +11120470
Telerik.Web.UI.GridGroupPanel.get_MainTable() +54
Telerik.Web.UI.GridGroupPanel.OnPreRender(EventArgs e) +56

Any ideas? This also happens for PDF and Word exports. The grid uses an ObjectDataSource with EnablePaging true and a SortParameterName. Other grid functions like sorting, filtering, paging, and grouping work as advertised. The exports are setup in the markup like this:

<ExportSettings Excel-Format="Html" Word-Format="Html" FileName="Batch"
IgnorePaging="true" HideStructureColumns="true" OpenInNewWindow="true" ExportOnlyData="true">

Problem with batch editing in Radgrid

Hi All ,

I am using Batch Editing for Insert, Update and Delete operations in my radgrid. I have taken reference from
http://demos.telerik.com/aspnet-ajax/grid/examples/data-editing/batch-editing/defaultcs.aspx.

I am facing a weird issue. When I try to delete the last row in the radgrid (or the underlying database table), the ItemCommand event of the grid
is not fired and hence it doesn't get deleted.
However, delete works fine in any other scenario.

Please help.

RadGrid Group Expand/Collapse not working properly on server mode

I am using the radgrid with group expressions to group and binding in the code. The expand works but collapse doesn't work on the same group. When I expand the other group, it collapses the previously opened group but when it collapse the expanded group, it doesn't work. I tried GroupLoad = "Client". It works but after few expand and close, the grid doesn't refresh and shows all grid lines all over.

What am I doing wrong?

Column size shrink with refresh

Hello,

I have a small problem every time I refreshed my page.

Indeed, the size of my columns shrink gradually, so that I can even do not see ...
Here are some screenshot:

First screen : http://puu.sh/eRxuj/ee67764f9a.png
After 5 refresh : http://puu.sh/eRxzR/6270233218.png

ColumnSeries columnEffluent = new ColumnSeries();

columnEffluent.Gap = 1.5;

columnEffluent.Name = "Effluents traités";

columnEffluent.LabelsAppearance.Color = System.Drawing.Color.Blue;

columnEffluent.Appearance.FillStyle.BackgroundColor = System.Drawing.Color.FromArgb(3, 133, 182);

columnEffluent.TooltipsAppearance.DataFormatString = "{0} m³/j";

LineSeries linePluvio = new LineSeries();

linePluvio.Name = "Pluviométrie";

linePluvio.AxisName = "AdditionalAxis";

linePluvio.MarkersAppearance.BorderColor = System.Drawing.Color.Red;

linePluvio.MarkersAppearance.BackgroundColor = System.Drawing.Color.Red;

linePluvio.Appearance.FillStyle.BackgroundColor = System.Drawing.Color.Red;

linePluvio.LabelsAppearance.Color = System.Drawing.Color.Red;

linePluvio.LineAppearance.LineStyle = Telerik.Web.UI.HtmlChart.Enums.ExtendedLineStyle.Smooth;

linePluvio.TooltipsAppearance.DataFormatString = "{0} mm";

Hope you can help me
