[Solved] Sort arrows always showing

I would like to have the arrow that shows up when a column is sorted to always show up. That way people will know that they can click on the header and sort the column. I have looked at a bunch of posts, but what happens is a sort image arrow shows on the last column I define, not all of them. one of the posts I looked at

Thanks, Amy

radajaxmanager and radajaxpanels

I have a question that I am sure has been asked.

I inherited am asp.net web application using manu of the Telerik controls. We use a master page and I just noticed (after nearly 3 years) that there were radajaxpanels embedded in the master page. All of our pages/controls use the RadAjaxManager (which is also defined on the master page) along with the RadAjaxManagerProxy on all pages.

I have removed the two radajaxpanels and I don't see any adverse impact on the application. Is there anything I should be looking for because I removed the Panels? Also, will it make a difference in performance? It seemed like the proxy was working since we use a radajaxloading panel and it seems to show up on the appropriate controls when I specify them in the proxy. I am wondering if it was really posting back the whole page even though it looked like it was the area I defined in the proxy.

Thanks.

Select All checkbox checked after sort

var selected = {};

function dgGrid_RowSelected(sender, args) {

var cpayID = args.getDataKeyValue("ID");

if (!selected[cpayID]) {

selected[cpayID] = true;

}

function dgGrid_RowDeselected(sender, args) {

var cpayID = args.getDataKeyValue("ID");

if (selected[cpayID]) {

selected[cpayID] = false;

}

function dgGrid_RowCreated(sender, args) {

var cpayID = args.getDataKeyValue("ID");

if (selected[cpayID]) {

args.get_gridDataItem().set_selected(true);

}

function dgGrid_Created(sender, eventArgs) {

var masterTable = sender.get_masterTableView(),

headerCheckBox = $telerik.$(masterTable.HeaderRow).find(":checkbox")[0];

if (headerCheckBox) {

headerCheckBox.checked = masterTable.get_selectedItems().length == masterTable.get_pageSize();

}

I am using the above code to update the selections made across pages. When I turn on sorting, and check just the first row, and then sort, when the grid refreshes, the single row is checked, but also the select all checkbox at the top is checked.

GridCheckBoxColumn AutoPostBack

I have enabled the GridCheckBoxColumn's checkboxes during the ItemDataBound event. Thus the client can click the (otherwise disabled) checkboxes. Although I have set the AutoPostBack=true and added a handler for the CheckedChanged event I receive no postback.
Please advice (v2013.2.717.35).

Calender in RadDockZone

Hi Everyone,

I m newly working on Rad Controls. So, please clarify me on my below requirements.

1. Can we add Calender (Dynamic) directly to RadZone. or we have to do it through RadDock.???
2. I need calender to start from current month with only right arrow beside it. Only clicking this right arrow, we have to navigate to next month and at the same time left arrow should be enabled.
3. Is Calendar can be minimized ???

Its would helpful for me if you suggest anything for above. Atleast some hints.

Thanks and Regards

RadGrid custom filter does not generate the .aspx.designer files

Hello,

I implemented your solution for a custom column filter from the link below:
http://demos.telerik.com/aspnet-ajax/grid/examples/programming/filteringtemplatecolumns/defaultcs.aspx

This works when running it, but it has a big problem (I'm on VS 2008 SP1): the .aspx.desginer file does regenerate anymore!
I tried deleting it, and then Convert to Web Application from the .aspx file (which should generate the .aspx.designer file), but I got the error:
"Generation of designer file failed: unknown server tag <custom ...."
Once I remove this tag (<custom....), the generation of .aspx.designer file works very well.

Thanks,
Toni
