Hide Tab Clientside

I'm not getting an error and the alert shows the correct tab ID, any ideas why the tab is not hiding.

function HideHistoryTab(sender, e)
{
	var tabIndex = sender.get_activeTabIndex();
	if (tabIndex == 0 || tabIndex == 1)
	{
		var tabStrip = $find(_TabClientID);
		var tabs = tabStrip.get_tabs();
		//alert(tabs[3].get_id());
		tabs[3].set_visible(false);
	}
}

Postback on row selection in rad grid

I am dealing with a scenario where in grid , whether user clicks on a row or uses up/down arrow in the grid to select a row, it should do a postback and update other fields on the page. During research I have found that EnablePostBackOnRowClick and AllowKeyboard Navigation cannot work at the same time. This is what I have :

function GridRowSelected(sender, args) {

// do a post back to update other controls on the page

}

Can someone please help me in achieving this? I have tried different methods explained in forum but nothing worked for me. In short, I want it to do a post back when either user clicks on a row or make a selection using keyboard navigation and call this:

void RadGrid1_SelectedIndexChanged(object sender, EventArgs e)

{

}

Using Radgrid row drop to change sort order in database

Hi,

I'm trying to use the RowDrop method of the Radgrid to change the sort order in the database. Each row in the database table has a "SortOrder" column to indicate the order in which items should appear.

I want to allow the user to quickly change these orders.

Do you have any code samples that could easily do this? The example provided online doesn't seem to address this.

Thank you!

The process cannot access the file because it is being used by another process.

Hello.

I'm trying to save files in DB, which should record the file as "BinaryData".

I'm using RadAsyncUpload, but when i upload the file i get the extension "System.IO.IOException: The process cannot access the file because it is being used by another process." and the file only gets loaded in the App_Data folder of my app, in an automatically created "RadUploadTemp" folder.

I've tried to disable the Path mentions in my SaveFile method, getting "Path not found error". Any of the available telerik demos is similar to my context.

How do i solve this?

//my insert/update operations method
public void SaveFile(object sender, EventArgs e)
        {
            ListagemTimesheet model = new ListagemTimesheet();
            model.IDRecursoHumano = Convert.ToInt32(rdpInvestigadorE.Text);
            model.IDEstadoTimesheet = Convert.ToInt32(rcbEstado.SelectedValue);
            model.Observações = Obervaçoestxt.Text;
            model.AssinaturaTimesheet = txtAssinaturaTimesheet.Text;
            model.DataEnvio = DataEnvio.SelectedDate.Value;

            if (!string.IsNullOrEmpty(Ficheiro) && FileTipo != null)
            {
                model.Ficheiro = Path.GetFileNameWithoutExtension(Ficheiro);
                model.FileContent = fileBytes;
                model.FileTipo = Path.GetExtension(FileTipo);
            }
            if (!string.IsNullOrEmpty(FileID.Text) && Convert.ToInt32(FileID.Text) > 0)
            {
                model.ID = Convert.ToInt32(FileID.Text);
                listagembll.UpdateFile(model);
            }
            else
            {
                listagembll.InsertFile(model);
            }

Command Item Insert event

Hello

I'm trying to perform insert operation in a RadWindow. My scenario integrates the searchbox selected value, which should not be editable and automatically filled in insert, and for the rest, the normal empty fields, including the primary key.

I've already done the edit operation, with the following structure, but i cannot modify properly to the insert. Besides, when i push Insert button, i get the last assinged values, as the radwindow does not perform reload

Could you help me please?

 public void SaveFile(object sender, EventArgs e)
        {
            ListagemTimesheet model = new ListagemTimesheet();

            model.IDState = Convert.ToInt32(rcbEstado.SelectedValue);
            model.Obs = Obstxt.Text;
            model.Assin = txtAssin.Text;
            model.Date = Date.SelectedDate.Value;

            if (Objecto.ID > 0)
            {
                model.ID = Convert.ToInt32(FileID.Text);

                if (!string.IsNullOrEmpty(FileID.Text) && Convert.ToInt32(FileID.Text) > 0)
                {
                    model.ID = Convert.ToInt32(FileID.Text);
                    bll.UpdateFile(model);

How to add button with arrow to AutoCompleteBox for showing dropdownlist?

I would like to have a button with arrow image inside AutoCompleteBox (this control will be created in code behind), so after pressing it the dropdownlist with current text matching items would show up (if no text is present, then the first X number of items). I have the control already made in Winforms (using your Winforms components, attachment shows the winform's control look), so I was wondering if the same can be made in ASP.NET?

(btw: if you want to see the code of my Winform's control then you can see in this thread: https://www.telerik.com/forums/click-event-not-firing-for-autocompletesuggesthelper-popup-of-raddropdownlist )
