RadAjaxManager makes our application slow

Hi,

We are using the Telerik controls version 2012.3.1308.40(licensed) on our web site. We are using the RadAjaxManager in almost all pages with RadAjaxLoadingPanel.

We initially had pagination in all rad grids. But the user does not like the pagination and wanted to use the scrolling instead. So we removed pagination from all grids and enabled scrolling,
<ClientSettings>
<Scrolling AllowScroll="True" UseStaticHeaders="True" SaveScrollPosition="true" />
<ClientEvents OnGridCreated="GridScrollCreated" />
</ClientSettings>
We have some grids with item template to capture user input (3 columns only). Approximately we may get 200 to 300 records from the database when binding the grid. After making this change, we have encountered a new problem that our application become very very slow. For each post backs the loading panel is running for more than 3 minutes. After the post back the grid is not rendering properly and further post back are not working.

please see the attachment

Grid content size doesn't account for vertical scroll bars on IE7

We have a web application that uses grids and needs to target IE7 up to IE10.

On IE7, if the grid has enough data to show a vertical scrollbar, the grid header resizes itself to account for the width of the scrollbar on the right hand side but the content area doesn't. This means that the scrollbar is over top of the content in the right hand column of the grid, and the grid headers no longer line up with the columns in the grid.

We are using a custom skin for these grids.

Is there a fix or recommended work around for this?

Thanks
Enjoy

Is it possible to ignore capitalization in results?

Something we've noticed about the PivotGrid is that it treats different capitalization as different values in the result set. For example, if I have values of;

Bun Maker
Bun maker
bun maker
BUN MAKER
BuN mAkEr

...these will each be treated as different/unique values. Is there a way to ignore capitalization and treat all similarly-spelled entries as the same? We thought about applying standard spelling at source, but making everything upper or lower case doesn't look right.

Menu item collapse

hello,

I'm using radmenu.

Occasionally, on hovering over a menu item, after the menu has been loaded, the menu expands and collapses immediately.
After several trials, the menu returns to it's normal behaviour( Note that, the wrong behaviour returns after some time).

Please help...

GridBoundColumn ItemStyle

Hi There

I have a problem with GridBoundColumn ItemStyle as it does not behave like GridBoundColumn HeaderStyle. I have made this simple class to provide my own inherited version og GridBoundColumn:

using System.Web.UI.WebControls;
using Telerik.Web.UI;

using System.Web.UI.WebControls;

using Telerik.Web.UI;

namespace LWTelerikGrid.Extenders.ColumnExtenders

{

public class LWBooleanBoundColumn : GridBoundColumn

{

public override TableItemStyle HeaderStyle

{

get

{

TableItemStyle tableitemstyle = base.HeaderStyle;

tableitemstyle.HorizontalAlign = HorizontalAlign.Center;

return tableitemstyle;

}

public override TableItemStyle ItemStyle

{

get

{

TableItemStyle tableitemstyle = base.ItemStyle;

tableitemstyle.HorizontalAlign = HorizontalAlign.Center;

return tableitemstyle;

}

public override bool AutoPostBackOnFilter

{

get

{

return true;

}

I use the LWBooleanColumn like this:

<LWColumnExtenders:LWBooleanBoundColumn DataField="LicenseRequired" DataType="System.Boolean"

FilterControlAltText="Filter LicenseRequired column" HeaderText="LicenseRequired"

SortExpression="LicenseRequired" UniqueName="LicenseRequired">

</LWColumnExtenders:LWBooleanBoundColumn>

When I use the VS 210 debugger, I can see that the HeaderStyle property is activated, but the ItemStyle property is left untouched.

Why is that ?

Thanks in advance for any tips...

Thomas, Copenhagen.

RadGrid expand after filter

Hi, all!
I have an RagGrid. To this grid, I use AllowFilteringByColumn = true and GroupByExpression to some columns. But, I need this RadGrid result, expand after a filter, without grouping.

How make the RadGrid result expand after filter?

My code.

<script type="text/javascript">

(function () {

var demo = window.demo = {},

autoCompleteBox,

masterTableView;

demo.GridCreated = function (sender, args) {

masterTableView = sender.get_masterTableView();

}

demo.AutoCompleteLoaded = function (sender, args) {

autoCompleteBox = sender;

}

demo.EntryAdded = function (sender, args) {

filterGrid();

}

demo.EntryRemoved = function (sender, args) {

filterGrid();

}

function filterGrid() {

if (!masterTableView || !autoCompleteBox) return;

var entries = autoCompleteBox.get_entries();

if (entries.get_count() === 0) {

masterTableView.expandAllGroups();

return;

}

masterTableView.collapseAllGroups();

$telerik.$(masterTableView.get_element()).find("td").filter(function () {

for (var i = 0; i < entries.get_count(); i++)

if ($(this).text().indexOf(entries.getEntry(i).get_text()) !== -1) return true;

return false;

}).closest(".rgRow, .rgAltRow").each(function () {

masterTableView.expandGroup(this);

});

}

window.pageLoad = function () {

$(masterTableView.get_element())

.find(".rgGroupHeader td")

.not(".rgGroupCol")

.css("cursor", "pointer")

.click(function () {

masterTableView.toggleGroup($(this).closest("tr")[0]);

});

}

})();

</script>

[Solved] ConfirmTextFields with client side binding

Hi to all,
I have a grid where I use GridClientDeleteColumn (or GridButtonColumn). I would like to use confirmation dialog with the parameters relating to the row data. ConfirmTextFields property works well with server bindings for me. Unfortunately, when binding the grid on the client side using WCF service, the required row data (Shortcut and Text in my example) are blank in the confirmation dialog. What should be done to show the fields of ConfirmTextFields property if I use the web service bindings?

<telerik:GridClientDeleteColumn Reorderable="false" ButtonType="ImageButton" CommandName="Delete"

UniqueName="DeleteColumn" ConfirmDialogType="RadWindow"

ConfirmTitle="Question" ConfirmTextFields="Shortcut,Text" ConfirmTextFormatString="Country {0} - {1} will be removed">

</telerik:GridClientDeleteColumn>

Thanks
-Marian
