Hello

I have to display a list of parameters with a hierarchic relation between them. I use a RadTreeList and it works fine.
My tree list has a "Value" column.

I would like to change some values in this column but I don't want to make the changes row by row (by entering in edit mode, making modification and updating). I'd prefer to keep all the rows in edit mode, make the modifications in some of them and validate by clicking on an external button.

I didn't find something like that in the demos.

 I tried to use an ItemTemplate for the edit column.

The display is correct but when there is a postback, the data are reloaded. So I would like to keep the modifications in a dictionary in order to overwrite the bound values.


My problem is that I can't get the event when a textbox is modified (to save the new value in the dictionary. I added:
AutoPostBack="true" OnTextChanged="tbxValue_TextChanged"  in my template textbox description but the method is never called.

Has anyone an idea to solve my problem or to provide another way to implement my feature  (without ItemTemplate and edit mode) ?

Thank you

How do I get the menu text of the menu item selected with client side code?

Thanks

I have a radgrid that 1. I cannot highlight the row on clicking and 2. the selectedindexchanged event does not fire.  The grid sits inside an update panel and is loaded when a user select a value from a combo box, which is passed as a parameter to a stored procedure.  The grid load without problem, but as mentioned once loaded I cannot click on the row and highlight the row and the selectedindexchanged event does not fire.  Below is the grid settings.  I have also tried  to add the following code on the page load, but this has not helped.
 this.grdItems.ClientSettings.EnablePostBackOnRowClick = true;
this.grdItems.ClientSettings.Selecting.AllowRowSelect = true;

Any suggestions?

Hi Telerik, 

I posted a thread a couple of days ago and I thought I had solved my problem but turns out I just moved it.

My problem now is that I have template columns that contain buttons and others that have text that needs to be on a different color depending on the status of the item.

So basically, I used to bind my grid using the 'simple way' (Create data table, add source to the grid and bind)
Once it was bound, I would go through each rows, set the text to the button and set the appropriate CSS on the text label. 

Since I needed to sort and to filter, I saw that I could use the 'OnNeedDataSource' event, which is the second way to bind a grid.

This worked and I could sort/filter my grid.

But now, after the event is called, I tried to change the CSS and the text again but it says that the grid doesnt have any items.

I believe its because it wasnt bound (even though I can see the rows once everything is done)

Hi,

If I use a grid smart tag to edit the EditTemplate and drag a control into the edit box provided, it produces this code in <MasterTableView>:


but when my template opens it shows nothing, basically just a title bar with no content. When I use the code below (which I got from your website) then the template shows up just fine - so just what is EditItemTemplate all about?

Good morning.

This is my first post, so I will do my best to cover everything as thoroughly as possible. I am implementing a RadGrid in an ASP.NET project. Here are the particulars:

Windows 7
IE 11
ASP.NET 4.5
preferred language is VB
latest version of Telerik Tools

I have followed the instructions of several examples I've found online, including some here, but to no avail. No matter what I do, when I click any button in my RadGrid - Add, Edit, Cancel, etc. I get a PostBack. After clicking any button, all subsequent attempts to interact with the RadGrid fail due to the postback. I just want to use AJAX. Here is my RadGrid code:


Here is my Ajax Manager code (my primary RadAjaxManager is in the Matser page):


I am fairly new to using Telerik (and .NET in general), and I'm on a tight deadline. Any assistance would be appreciated - thanks.

Respected Sir/M'am,

we are currently facing an issue in RadAsyncUpload where :
1)  After the file is uploaded, if any postback occurs (may it

be a cancel button postback or any other control postback) the

uploaded file is directly moved to the target folder



Is there any solution where on specified control click only ,

the uploaded file can be moved to target folder else it will

persist as it is uploaded.

I have set the number of rows per page to 15.  When I have fewer than 15 rows the footer is not displayed.  When I have more than 15 row the footer is displayed with the various counts and navigation buttons are displayed.  ( Page 1 of 34, items 1 to 15 of 500)  My client wants the footer displayed when less than 15 records and have a count  something like the following.   (Page 1 of 1, items 1 to 10 of 10)  I defined my grid as follows.

            RadGrid1.ID = "RadGrid1";
            RadGrid1.DataSourceID = "SqlDataSource1";
            RadGrid1.MasterTableView.DataKeyNames = new string[] { "Jobnumber" };
            RadGrid1.Skin = Theme;
            RadGrid1.EnableEmbeddedSkins = false ;
            RadGrid1.Width = Unit.Percentage(100);
            RadGrid1.PageSize = 15;
            RadGrid1.AllowPaging = true;
            RadGrid1.PagerStyle.Mode = GridPagerMode.NextPrev;
            RadGrid1.AllowSorting = true;
            RadGrid1.AllowFilteringByColumn = false;
            RadGrid1.AutoGenerateColumns = false;
            RadGrid1.ClientSettings.Resizing.AllowColumnResize = true;
            RadGrid1.ClientSettings.Resizing.ResizeGridOnColumnResize = true;
            RadGrid1.ClientSettings.Resizing.ClipCellContentOnResize = true;
            RadGrid1.ClientSettings.AllowColumnsReorder = true;
            RadGrid1.ClientSettings.ColumnsReorderMethod = GridClientSettings.GridColumnsReorderMethod.Reorder;
            RadGrid1.GridLines = GridLines.Both;
            
            RadGrid1.EnableViewState = true; 

            
            RadGrid1.ItemCommand += new GridCommandEventHandler(RadGrid1_ItemCommand);
            RadGrid1.PageIndexChanged += new GridPageChangedEventHandler(RadGrid1_PageIndexChanged);

Hi,

I have a radgrid in which i have placed the following controls
1)A RadTabstrip -with 2 pageviews (one for displaying a page and the another for displaying someother page)
2)someother page may not be visible based on the functionality most of the times. so i am checking for its visibility in itemcreated.
if visible false do not display the page 2
on clicking the expand collapse button it should expand /collapse the radgrid displaying the tabstrip.
3)added to this i have a validation in prerender event of the radgrid which has some validations as follows. means it reorders some columns and based on a condition makes few columns visible or not visible.

Here is the radgrid prerender event.
