Hi

How can I prevent a user to single click on a row (thereby changing the selected row). I only want the user to be able to double click on a row to change selected row.

I also want to programatically change row (I'm already doing this using set_selected(true);)

I have also changed the CSS for selected row (.rlbSelected) to show a background picture.

I've tried using some javascript to intercept SelectionIndexChanging and set_cancel(true); to prevent single click, but it still changes the focused row thereby causing other problems.

Override HeaderStyle Color

I build my grid in code

RadGrid RadGrid1 = new RadGrid();

RadGrid1.ID = "RadGrid1";

RadGrid1.DataSourceID = "SqlDataSource1";

RadGrid1.MasterTableView.DataKeyNames = new string[] { "Jobnumber" };

RadGrid1.Skin = "WebBlue";

//RadGrid1.EnableEmbeddedSkins = false;

RadGrid1.Width = Unit.Percentage(100);

RadGrid1.PageSize = 15;

RadGrid1.AllowPaging = true;

RadGrid1.PagerStyle.Mode = GridPagerMode.NextPrev;

RadGrid1.AllowSorting = true;

RadGrid1.AllowFilteringByColumn = false;

RadGrid1.AutoGenerateColumns = false;

RadGrid1.ClientSettings.Resizing.AllowColumnResize = true;

RadGrid1.ClientSettings.Resizing.ResizeGridOnColumnResize = true;

RadGrid1.ClientSettings.Resizing.ClipCellContentOnResize = true;

RadGrid1.ClientSettings.AllowColumnsReorder = true;

RadGrid1.ClientSettings.ColumnsReorderMethod = GridClientSettings.GridColumnsReorderMethod.Reorder;

RadGrid1.GridLines = GridLines.Both;

RadGrid1.ItemCommand += new GridCommandEventHandler(RadGrid1_ItemCommand);

RadGrid1.PageIndexChanged += new GridPageChangedEventHandler(RadGrid1_PageIndexChanged);

//Add columns

GridButtonColumn buttonColumn = new GridButtonColumn();

buttonColumn.HeaderText = "Select File";

buttonColumn.CommandName = "Select";

buttonColumn.ButtonType = GridButtonColumnType.PushButton;

buttonColumn.Text = "Go";

buttonColumn.ItemStyle.HorizontalAlign = HorizontalAlign.Center;

buttonColumn.HeaderStyle.Width = 50;

buttonColumn.HeaderStyle.BackColor = System.Drawing.Color.Crimson;

buttonColumn.HeaderStyle.BorderColor = System.Drawing.Color.Crimson;

RadGrid1.Columns.Add(buttonColumn);

I use the embedded Skin "WebBlue" However when I try to override the headerstyle color of the first column only half the header is changed.

Populating DropDownList in EditForm

Ihave a grid that is set to edit useing EditForms. On the ItemDataBound I fill the dropdownlist in the EditForm this works great for Inserting records. The issue is when I select and record from the grid to edit I use

<asp:DropDownList ID="ddState" runat="server" SelectedValue='<%# Bind("StateID") %>' />

So when I select the record the dropdownlist has not been populated yet. How can I populate the dropdownlist so I can set the select value.

Thanks,
Eric

Excel Export Column Widths with header title

I am trying to have the Excel export of my grid show the title from the header without expanding the first column of the data.
See attached screenshot

It is making my ID column very wide even though the column itself in the grid is defined to be narrow.
Is there anyway for my header title to appear in the export but not cause that first real data column to be so wide?
It does seem to work in the PDF because the PDF won't show my header title - I have only been able to show it as a Title of the page and not as an item in the grid header (which is a seperate issue).

The following is the code that I have tried to use to suggest that the title row should take two columns instead of just one.
I've set the title cell to use colspan="2" hoping that would transfer into the Excel file... but no luck as you can see.

<MasterTableView DataKeyNames="Id" DataSourceID="ClientDataSource" EditMode="PopUp"

CommandItemDisplay="Top" HeaderStyle-CssClass="grid_header">

<CommandItemTemplate>

<table width="100%">

<colgroup>

<col width="35px" />

<col />

</colgroup>

<tr>

<td colspan="2" style="font-size: 13px; padding: 10px 10px; text-align: left; white-space: nowrap; font-weight: bold">

<asp:Label runat="server" ID="lbl_reportName" Text="none">Client List</asp:Label>

</td>

<td class="flow_no_print">

<telerik:RadButton ID="btnAddNewClient" runat="server" ButtonType="LinkButton" BorderStyle="None" AutoPostBack="true"

CommandName="InitInsert" Text="Add Client">

<Icon PrimaryIconCssClass="rbAdd" PrimaryIconLeft="4" PrimaryIconTop="4" />

</telerik:RadButton>

</td>

<td class="flow_no_print" style="width: 160px; text-align: right;">

<asp:ImageButton Height="32" ID="ExportToPdfButton" CommandName="ExportToPdf" ImageUrl="~/images/icons/pdf.png" runat="server" ToolTip="Export to PDF" AlternateText="Export to PDF" />

<asp:ImageButton Height="32" ID="ExportToExcelButton" CommandName="ExportToExcel" ImageUrl="~/images/icons/excel.png" runat="server" ToolTip="Export to Excel" AlternateText="Export to Excel" />

<asp:ImageButton Height="32" ID="ExportToWordButton" CommandName="ExportToWord" ImageUrl="~/images/icons/word.png" runat="server" ToolTip="Export to Word" AlternateText="Export to Word" />

</td>

</tr>

<tr>

<td style="width: 35px;"></td>

<td></td>

</tr>

</table>

</CommandItemTemplate>

<Columns>

<telerik:GridEditCommandColumn UniqueName="EditColumn" ButtonType="ImageButton">

<ItemStyle Width="20" />

</telerik:GridEditCommandColumn>

<telerik:GridBoundColumn DataField="Id" DataType="System.Int32" HeaderText="ID" SortExpression="Id"

UniqueName="Id" Visible="true" ReadOnly="true">

<ItemStyle Width="35px" />

<HeaderStyle width="35px" />

<HeaderStyle width="200px" />

</telerik:GridTemplateColumn>

<telerik:GridCheckBoxColumn DataField="Active" DataType="System.Boolean" HeaderText="Active"

SortExpression="Active" UniqueName="Active" ReadOnly="false" Display="false" DefaultInsertValue="true" >

</telerik:GridCheckBoxColumn>

<telerik:GridButtonColumn ButtonType="ImageButton" UniqueName="ActiveColumn" HeaderText="Active" Display="false">

RadGrid with DetailsView

Hi everyone, i've been using radgrid for a couple of days now and i'm suppose to make an application using a radgrid with detailsview on each line. When i'll be clicking on an item from the grid, there will open the detailsview inside the grid. Actually i would like to make something similar to this application.

http://demos.telerik.com/aspnet-ajax/grid/examples/hierarchy/nestedviewtemplate/defaultcs.aspx

The only thing is that i would like to do it programmatically not from asp file.

So can you please tell me what do i need to do to make it work.

Dictionary Drop Down Width

Hi

I have had to add some custom values to the available languages in the dictionary drop down list, however I need to make the drop downs width much wider as the descriptions I have used for the languages look squashed.

I've been unable to find any help topics on this apart from trying to apply the popup width property to the control itself but this did not change the width.

I have attached a picture with an example of the drop down I am using and ideally would like the width to match the longest description.

Regards,
Jonathan
