Hey

I'm using Kendo Hierarchical grid, just as one of listed in your demos (http://demos.telerik.com/aspnet-mvc/grid/hierarchy). My issue is, I want to apply a filter on one of columns (on parent grid) such that it will also be applied on Child grid column. My issues are:

1. How do i know if there is filter applied on parent grid column, since there is no such even handler for filter on grid.
2. I want to data appear in child grid columns(if exists), even if entry doesn't exist on parent grid column

I did some experiments by passing the filter collection from parent grid to child grid (since both have similar schema), but again, but couldn't sort out the answers for those two questions

Thanks

Abdul Rehman

Telerik Rad Grid Add New Row on Client Side

Hi,
How to add new row in radgrid in client side. I have tried the following way
The Code is:
function addNewItem(sender,args) {
var MasterGrid = grid;
var masterTableView = MasterGrid .get_masterTableView();
var batchEditingManager = MasterGrid .get_batchEditingManager();
batchEditingManager.addNewRecord(masterTableView);
}

When I click the new row the row was created in radgrid. but the template column was not created also the index was set to -1,-2, etc...
In Radgrid we using shift click function so its throws script error.

I need to add multiple row one by one on rad button click not command button and I have one Rad Button checkbox template column in my grid how can I achieve this.

Excel Data Import and Save using BatchEdit Radgrid

Hello,

One of the requirement of our client is Excel export and Import data to radgrid. I am using RADGrid in BatchEdit mode,the data from the grid will be exported as excel. This has been done already using openxml. The data in the exported excel will be edited by the user. He may add new data. Once done the changes in the excel, the user wants to import the excel in Radgrid batchedit and save the changes in database.

In summary, the client wants to work offline with exported excel and then import the modified excel to the application.

How to do this import part in batch edit mode. Can you please share a sample project?

Creating RadDateTimePicker dynamically

Hi,

I have a requirement to create a number of server controls (e.g. asp textboxes etc.) as well as RadDateTimePickers dynamically (e.g. at runtime) on a webform. I'm using the same approach to create instances of both types of control (see below):

TextBox txt = new TextBox();

txt.ID = "someid"

txt.CssClass = "my-textbox-class";

ph.Add(txt); //add to placeholder control

RadDateTimePicker dtp = new RadDateTimePicker();

dtp.ID = "adifferentid";

dtp.Width = new Unit(200, UnitType.Pixel);

dtp.DateInput.CssClass = "my-datepicker-class";

dtp.TimeView.Interval = new TimeSpan(0, 30, 0);

dtp.TimeView.Columns = 6;

ph.Add(dtp); //add to placeholder control

Because they're created dynamically I recreate the controls every time there is a postback. I've noted that the regular asp controls maintain any values entered into them automatically after they're recreated however the RadDateTimePickers don't. Is there something I'm missing?

Thanks
