I have a RadGrid...

<telerik:RadGrid ID="RadGrid_1" runat="server" DataSourceID="EntityDataSource_1"
CellSpacing="0" GridLines=

"None"

AllowPaging="True" AllowSorting="True" AllowFilteringByColumn="True"
AllowAutomaticDeletes="True" AllowAutomaticInserts="True"
AllowAutomaticUpdates="True" Width="970px">

Im using the EditFormTemplate to show a table with various controls. some are simple text boxes others (dropdownlists) are bound to a different datasource to get predefined values form the DB.

Everything is working well, I can display a list of records, page, sort, filter, and edit a single record without a problem.
however, when I try to insert a new record i get a YSOD sayiing the selected value is not in the datasource
. in the case of the ddl the initial selected value would be "" and since that value does not exist in the datasource I can see why the error is thrown. I have mitigated this by adding in a bank listitem and appending databound items but this seems like a workaround and not a solution.

In the case of a telerik:RadDateInput...

<telerik:RadDateInput ID="RadDateInput44" runat="server" SelectedDate='<%# Bind("effectivedate")%>' />

im setting the selected date to a value from the radgrids datasource, again all of the features work until i try to insert a new record. Because the control is bound the selecteddate will be "" which cant be converted to a real date so i get a {"Specified cast is not valid."} exception.

How can this situation avoided on the insert and still have data bound controls on the edit/update
i was thinking of some kind of conditional binding expression but im not familiar with how to do that

Thanks, Scott

Suggestions for improvement in the Metro theme

Generally, the disabled text is far too pale; darken it.
In RadMenu, the border used for the hovered over item is indistinct; cnsider something else (a colour change?)
In RadMenu, the upper and lower border used for the selected item gets lost background; consider a better method of highlighting the item.
In RadGrid, the borders of the Pager buttons are too pale; consider using a darker colour.
In RadToolBar, the icons seem to ride higher in Metro than other skins (see ToolbarIcons-*.png)
In RadTreeView the expand node icon is too faint; consider making it darker.

RadGrid client side binding with more than 100 rows

Hi,

Please read my scenario described below.

Scenario: I have a RadGrid with approx. 10 GridTemplateColumns where in 9 template columns consists of RadTextBox and one template column has RadComboBox. The scenario is that this RadGrid is bound by more than 100 rows every time. Currently am using the client side programmatic binding method to bind the RadGrid.

Problem: I have observed that it is taking 2-3 minutes to bind the grid with more than 90 rows.

Can anyone suggest me on how to improve the performance? I want the RadGrid to be loaded in very quick time, say in around 5-10 seconds.
Any help would be greatly appreciated.

Thanks,
Sandeep

My RadScheduler is bound to a LinqDataProvider and automatically inserts, updateds and deleted appointments. Is there a way to perform inserts manually via a server side event? I have a custom field that I would like saved with each appointment which never needs editing. Thanks.

Radgrid Not Sorting

Hi All,

I have C# code-behind RadGrid that uses SQLDataSource and Databinds in NeedDataSource();

I have set

radGrid.AllowSorting = true;

radGrid.MasterTableView.AllowMultiColumnSorting = true;

radGrid.MasterTableView.AllowNaturalSort = true;

I have also set AllowSorting= true; on the columns themselves, but nothing seems to work. The columns refuse to sort, even though I can see the Arrow Up, Arrow Down and revert to default. Can you please help?

Thanks,
Mark

not getting new date entered in raddatepicker dateinput

Hi,
We have a RadDatePicker control. User can enter/edit manually date in the associated date input box. Then on a save button click we need to perform some validation. The problem is when user manually edits the date and presses enter key while still in the date text box, we do not get the selected date from the raddatepicker control. We need this new date value in the validation function. How can we resolve this ?

selecting radiobutton does a full page submit (instead of ajax)

I have two radio buttons on my aspx page, and when I click one, it does a full page submit. I need to implement Ajax functionality. How can I do that?

On my html page, I have a reference to the AjaxToolkit. Any suggestion?

The html code is:

<asp:Panel ID="pnlSelectAllItemsClearAllItems" Visible="true" runat="server" ScrollBars="None">

<table border="0">

<tr>

<td width="50%" style="height:2%;">

<asp:RadioButtonList ID="rbSelectAllItemsClearAllItems" runat="server" AutoPostBack="true"

RepeatDirection="Horizontal" Enabled="true"

OnSelectedIndexChanged="rbSelectClearAllItems_OnSelectedIndexChanged" >

<asp:ListItem Value="SelectAllItems">Select All Items</asp:ListItem>

<asp:ListItem Value="ClearAll">Clear All</asp:ListItem>

</asp:RadioButtonList>

</td>

<td style="text-align: center; height:2%;" width="50%">

<asp:Button runat="server" Text="Archive Selected Items"

ID="btnArchiveSelected" onclick="btnArchiveSelected_Click" />

</td>

</tr>

</table>

</asp:Panel>
