Setting column width using CSS

Hi there;

I have a grid with column definitions similar to the following:

<telerik:GridNumericColumn UniqueName="R1" Visible="true" ReadOnly="false" HeaderText="Q1" DataField="R1" DataFormatString="{0:0}%" HeaderStyle-CssClass="EntryColumn" ItemStyle-CssClass="EntryColumn" />

The EntryColumn class just has a simple width:30px definition, with nothing else.

The grid respects the column width until I add the Command Bar display - with that on, it reverts to just showing the columns in the default width. I can fix it using ItemStyle-Width, but I'd rather use a class definition as I have several of these types of grids scattered throughout the app.

Anybody know what I'm doing wrong?

Thanks,

Jason

Recurrence Error

I'm trying to generate the RecurrenceRule by code.

However, it failed when selecting "Monthly" and "The first day of every month"

The error can be reproduced in Telerik Demo Web Site:

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

1. Add a new appointment.

2. Click the "Option" button

3. Check the "Recurrence" checkbox

4. Select "Monthly"

5. Select "The first day of every 1 month(s)"

6. Click "Save"

7. There was an error generated.

In my project, I got the "Object reference not set to an instance of an object" error.

Thanks,

Wilson

RadGrid UseStaticHeaders with GridTemplateColumns

I've noticed some funny behavior when I combine the UseStaticHeaders and GridTemplateColumn configurations for the RadGrid.

The grid loses the header and the detail disappears on occasion as well.

Here is a snippet of code:

<telerik:RadGrid

runat="server"

ID="gridSample"

AutoGenerateColumns="false"

ShowHeader="true"

ShowFooter="false"

OnItemDataBound="gridSample_ItemDataBound"

OnNeedDataSource="gridSample_NeedDataSource"

>

<ClientSettings>

<Scrolling AllowScroll="true" ScrollHeight="400px" UseStaticHeaders="true" />

</ClientSettings>

<MasterTableView EnableNoRecordsTemplate="true">

<NoRecordsTemplate>

<asp:Label runat="server" Text="There is no file to review" />

</NoRecordsTemplate>

<Columns>

<telerik:GridTemplateColumn HeaderText="Name" UniqueName="Name">

<ItemTemplate>

<asp:Label runat="server" Text='<%# Eval("LastName") + ", " + Eval("FirstName") + " " + Eval("MiddleName") %>' />

</ItemTemplate>

<ItemStyle Width="45%" HorizontalAlign="Left" />

<HeaderStyle Width="45%" HorizontalAlign="Left" />

</telerik:GridTemplateColumn>

.

</Columns>

</MasterTableView>

</telerik:RadGrid>

I believe the sticking point is the use of static headers with the grid template columns. If I remove either the template columns or the UseStaticHeaders declarative, the problem goes away.

This is an older app that i am supporting and it is using the 2015.1.225.35 version of the assembly.

RadGrid Batch Edit - Prevent navigating to next row

I am using a RadGrid with batch edit mode. I want to have keyboard navigation turned on so that a user can tab through the columns in the current row. When this is turned on the default behavior is that when a user hits tab on the last control of a row, when there are additional rows in the grid, the user is navigated to the next row. What I want to prevent is the navigation to the next row when the last control in the edited row is currently being edited and the user presses tab. Is this possible? Is it possible to save that row edit if tab is pressed on that last control?

Thank you for your time.

give me some advice on search speed which method is the best

Hello

in a combobox the user writes the city and the program should search for this city according to written characters obviously do a search in a sql table that has over 9000 records. I set of keywords to speed everything but I ask you, which of the two methods of code is more powerful?

Protected Sub luogoresidenza_ItemsRequested(sender As Object, e As RadComboBoxItemsRequestedEventArgs) Handles luogoresidenza.ItemsRequested

Using Context As New touristEntities

If Not [String].IsNullOrEmpty(e.Text) Then

Dim Query = (From c In Context.Tab_comuni_nazioni

Where c.c_descrizione.StartsWith(e.Text)

Order By c.c_descrizione

Select c.c_idrecord, c.c_descrizione).ToList

Dim query1 = Query.Skip(e.NumberOfItems).Take(10)

luogoresidenza.DataSource = query1

luogoresidenza.DataBind()

Dim endOffset As Integer = e.NumberOfItems + query1.Count()

Dim totalCount As Integer = Query.Count()

If endOffset = totalCount Then

e.EndOfItems = True

End If

e.Message = [String].Format("Items <b>1</b>-<b>{0}</b> out of <b>{1}</b>", endOffset, totalCount)

End If

End Using

End Sub

Or better to use a web service?

UpdatePanel

I'm experiencing an issue getting my UpdatePanel to work properly in a C# ASP.NET project. It's identical code to multiple other pages in my solution, but has unusual behavior on this page. The goal is simply to allow the user to change a radio button which then alters the visibility of various table rows further down in the UpdatePanel. Interestingly enough, the CheckBox works as expected.

In my current page, I have the following code:

<asp:UpdatePanel ID="updatePanel" runat="server" UpdateMode="Conditional">

<ContentTemplate>

<span class="stepTitle">Set Fluid Properties</span>

<div class="calculateInnerDiv">

<asp:RadioButtonList ID="FluidTypeList" runat="server" AutoPostBack="true" RepeatDirection="Horizontal" TabIndex="101" OnSelectedIndexChanged="FluidTypeList_Changed">

<asp:ListItem Text="" Value="Liquid" />

<asp:ListItem Text="" Value="Gas" />

<asp:ListItem Text="" Value="Steam" />

</asp:RadioButtonList>

<asp:CheckBox ID="IsCompressibleCheckBox" runat="server" AutoPostBack="true" Text="Fluid Is Compressible" Checked="<%# model.isCompressible %>" TabIndex="101" OnCheckedChanged="IsCompressible_Changed" />

.

However, when it renders, there is an extra RadAjaxPanel that is being created, as seen below. This panel does not get generated in any of the other pages with a similar process. Due to the extra panel, I receive a JS error of "Uncaught TypeError: Cannot read property 'id' of null" in "Telerik.Web.UI.WebResource.axd:3776". It also displays "867|updatePanel|ctl00_ctl00_mainHolder_FluidTypeListPanel|" on the page.

<div id="mainHolder_updatePanel"> 

<span class="stepTitle">Set Fluid Properties</span>

<div class="calculateInnerDiv">

<div class="RadAjaxPanel" id="ctl00_ctl00_mainHolder_FluidTypeListPanel"> 

<table id="mainHolder_FluidTypeList">

<tr>...</tr>

</table>

</div>

<input id="mainHolder_IsCompressibleCheckBox" type="checkbox" name="ctl00$mainHolder$IsCompressibleCheckBox" onclick="javascript:setTimeout('__doPostBack(\'ctl00$mainHolder$IsCompressibleCheckBox\',\'\')', 0)" tabindex="101" />

.

For my codebehind, I run a case statement that hides/displays certain fields based on the selection, and then it calls updatePanel.Update(). Any suggestions are absolutely welcome as I'm at my wit's end on this.

Thank you for your time.
