RadGrid Filtering

Not working for some reason in version 2012.3.1308.35

Getting different error details but essentially boils down to 0x800a139e - JavaScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: is neither a DataColumn nor a DataRelation for table .

MasterTableView has AllowFilteringByColumn = "true"...

DataTextField is set to column name from datatable so binding works fine...

Using inside usercontrol with RadAjaxManager (Not the Proxy control)

Becoming a frustrating thing...lol

Any Ideas???

Thanks,

Tim

AJAX Driven Paging Broken after Upgrade

We have updated Telerik from 2010.3.1109.35 to 2018.1.177.45 and also our Website from .NET 3.5 to .NET 4.7

We now find that our AJAX driven paging on our User Controls is no longer working and it ends up just posting back rather than updating the User Control.

For example, when clicking the Page Right button or jumping to a page the Loading Panel is displayed but then a full page refresh occurs and nothing has updated.

how to get if combobox selected item is null with javascript?

hey everyone,

I want to validate a button such that if combobox selected items count is equal to zero then button click will show an alert on client side. I am doing this:

function filterSearch()

{

var combo = $find('<%=RadComboBox1.ClientID %>');

var textbox = document.getElementById("txtSearch");

var selectedItemsCount = combo.get_selectedItems().length;

if (selectedItemsCount == 0)

{

alert("You must select a category before processing search!");

return false;

}

This ain't working though. This is my button:

<asp:Button ID="btnSearch" runat="server" Style="float: left; color: black; font-weight: bold" Text="Search" OnClick="btnSearch_Click" OnClientClick="javascript: return filterSearch();" />

How can I do this?

Thanks,
Amit

</ItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

</MasterTableView>

<PagerStyle Mode="NextPrevAndNumeric" />

</telerik:RadGrid>

</div>

Then I created C# code to filter the Grid by user and or Role with this code. I am not showing all of the code just enough to give a picture of what I am working with:

if (txtName.Text.Length > 0 && ddlRole.SelectedIndex == 0)

{

string a = txtName.Text;

using (ExpungeEntities db = new ExpungeEntities())

{

RadGrid1.DataSource = db.USERS_T_DATA.Where(c => c.FirstName.Contains(a)

|| c.LastName.Contains(a)).ToList();

{

RadGrid1.Rebind();

int intGridCount = RadGrid1.Items.Count;

if (intGridCount == 0)

{

DisplayMessage("No records matched your search");

txtName.Text = string.Empty;

}

The code works as expected and I endup with a filtered grid. but here is the issue I am trying to solve. When I click the "edit" icon that was created by my use of the AllowAutomaticUpdates I am presented with the first row in the grid for updating instead of the intended row. I have taken a screen shot that shows the issue to help explain.

How can I get the correct row to display for edit?
