Please disregard my thread below. I converted all my <images> to <asp:images> and put them into the controls collection to get what I needed. Lots of work but a better result.

Anyway, I'm attaching a project that won't pick up my customized styles if I set them at runtime. If I set them at design time they get picked up and work just fine.

When I dynamically add 10 images and set them each with one of 4 custom styles it has a clear tooltip with transparent everything except text. 

Thanks in advance!

I am using Schedular control as readonly to list the all ppointments from database. It displays all appointments. It gets refresh once I clicked on an appointment. After that all events of scheduler doesn't work. I am using in my asp.net master page. What might be the issue here.

I've been looking into ways of doing filtering in a RadGrid by simply selecting a foreign key from a dropdown-list, like "Categories", "OrderStatus" etc. but no matter how hard I look, I can't seem to find a solution that doesn't feel very complicated, for what should really be one of the most common tasks used with a Grid. The other solutions probably work, but they seem over complicated, and thus harder to maintain over time etc.RadGrid has so many exceptional features, like most of the support for filtering, that it is very odd that it seems to almost lack support for what must be one of the most common tasks - filtering based on dropdowns.

When googling for this, I happend to stumble upon this blog entry, which I think really sums it ut very well, so instead of writing the same thing here all over again, I just refer just to http://www.tunaslut.com/telerik-radgrid-and-filtering-on-listtextfield-with-a-griddropdowncolumn/ and humly ask if there is still no easy way of doing this as of October 2010?

What is the recommended way of implementing simple drop down filtering? I've must have seen examples/code only on the Telerik site describing at lest 3-4 different ways of doing it (client side, serverside, custom class etc) and I am guessing that perhaps some of them are mainly vaild for older versions of the Telerik controls, lacking the features of the latest versions.

Hi, 

I have 2 grids on the web page, which I put into RadAjaxManager



Both of them have detail tables and I obtain data through NeedDataSource with similar content =>

if (e.IsFromDetailTable || e.RebindReason == GridRebindReason.InitialLoad)

  return;

  

RadGridResultsTest.DataSource = GetMainData();

First grid works fine and when I try to go to next page or change pagesize everything works correctly because all the time I obtain GridRebindReason.PostBackEvent in NeedDataSource method.

On the other hand second grid will display data only after button click, because there is GridRebindReason.ExplicitRebind
but during paging I obtain all the time GridRebindReason.InitialLoad, which makes my grid disappear. I also tried to remove condition


so paging was suddenly working. I had 3 pages with 26 rows. I changed pagesize to 15 so I had 2 pages. But when I clicked on second page, grid somehow restored to pagesize 10 and got itself to first page.

Do you have any idea, where can be the problem and how can I make this work ?

Thanks a lot.

Hi Team,

Can we disable and Enable the Rad Grid Paging Buttons .

If I am In 1st page then we have to disable Previous and First buttons

similary If we are in last page then we have to diable Next and Last buttons

and

Can we show tool tips for Grid page index numbers 1,2,3................

please give ur advise as soon as possible ....

Regards,
Prasad

Dear
i need to save settings for grid but in same time i have my paging
 code :

public void CustomizedGridPagerSize(GridItemEventArgs e) {
        int allItemsCount = (e.Item as GridPagerItem).Paging.DataSourceCount;
        RadComboBox combo = (e.Item as GridPagerItem).FindControl("PageSizeComboBox") as RadComboBox;
        RadComboBoxItem item1 = new RadComboBoxItem("10", "10");
        RadComboBoxItem item2 = new RadComboBoxItem("20", "20");
        RadComboBoxItem item3 = new RadComboBoxItem("50", "50");
        RadComboBoxItem item4 = new RadComboBoxItem("100", "100");
        RadComboBoxItem item5 = new RadComboBoxItem("200", "200");
        RadComboBoxItem item6 = new RadComboBoxItem("All", allItemsCount.ToString());
        item1.Attributes.Add("ownerTableViewId", e.Item.OwnerTableView.ClientID);
        item2.Attributes.Add("ownerTableViewId", e.Item.OwnerTableView.ClientID);
        item3.Attributes.Add("ownerTableViewId", e.Item.OwnerTableView.ClientID);
        item4.Attributes.Add("ownerTableViewId", e.Item.OwnerTableView.ClientID);
        item5.Attributes.Add("ownerTableViewId", e.Item.OwnerTableView.ClientID);
        item6.Attributes.Add("ownerTableViewId", e.Item.OwnerTableView.ClientID);
        combo.Items.Clear();
        combo.Items.Add(item1);
        combo.Items.Add(item2);
        combo.Items.Add(item3);
        combo.Items.Add(item4);
        combo.Items.Add(item5);
        combo.Items.Add(item6);
        combo.Items.FindItemByValue(((RadGrid)e.Item.OwnerTableView.Parent).PageSize.ToString()).Selected = true;
    }

if we use the default paging sizes then it is working well and we can load the grid settings,
but when we use the code above to increase the paging sizes then when we load the grid settings we found the pager not saved

Hi,
I'm long time Telerik controls user. I'm generally very hapy with them, but I miss one thing. Integrated RadTextBox property which set RadTextBox as Required. When you create long forms, you have two ways how to implement validation:

• put and configure asp:RequiredFieldValidator to each RadTextBox. It is very painful work and you will end with very messy code
• use RadInputManager with Validation IsRequired="true". This approach is good, but it's working only with classic TextBoxes, not with RadTextBoxes. And then I miss eg. possibility to define different EmptyMessage texts for each control.

My dream RadTextBox could be this one (meaning of new parameters is obvious):

I'm not developing wheel for now, those parameters are used in this ExJS implementation:
http://extasp.net/#/form/form_validate.aspx
Their TextBox works absolutly amazing. When non-valid, it sets itself into red, displays explanation bubble etc...

I'm able to achieve this behavior with RadTextBox also, but it will cost a lot of Javascript, implementation of RadToolTip etc. And I'm talking about speed! R.A.D.! :-) I just want to put required="true" into RadTextBox tag and everything is set.

Is there some way how to work with RadTextBox (...RadNumericTextBox, RadMaskedTextBox...) in simillar way?

Thank you very much for your advise.
Zdenek

I'm missing the old classic interface for ASP.NET AJAX demos. In the new one some code is missing and cant find the links to community and support, Why have you changed something that it was just fine? Perhaps is to implement that green-black amazing color combination?  :-P
