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!

I'm trying to remove the vertical scroll bar from a radgrid. I'm not enabling paging and don't want to show the vertical scrolling. I only need the horizontal function. Any help would be appreciated.

Thanks

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.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);

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.Assin = txtAssin.Text;
            model.Date = Date.SelectedDate.Value;

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

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 )

how to change tabstrip colors?

as far as I understand the tab colors are dictated by an image and can't be changed using css alone, you'll need to change the image, so how would I for example change it from the default black to a blue?

Read updated colors from a grid

Hiya,

I have a grid with a template column that contains a RadColorPicker. I would like to read the color values in a postback. However, using the code below, I'm only getting the values from the original data source.

ASPX:

<telerik:RadGrid ID="grdUser" runat="server" AllowMultiRowSelection="true" AutoGenerateColumns="false" ShowStatusBar="true"
            AllowSorting="True" AllowFilteringByColumn="true"
            OnItemDataBound="grdUser_ItemDataBound">
            <MasterTableView DataKeyNames="UserId, UserName, HexCode" CommandItemDisplay="None">
                <Columns>
                    <telerik:GridClientSelectColumn UniqueName="ClientSelectColumn" HeaderStyle-Width="40px"/>

                    <telerik:GridBoundColumn UniqueName="UserName" HeaderText="Name" DataField="UserName" /> 

                    <telerik:GridTemplateColumn DataField="HexCode" HeaderText="Route Colour" UniqueName="HexCode">
                        <EditItemTemplate>
                            <telerik:RadColorPicker ID="editColor" runat="server" SelectedColor='<%# Bind("HexCode") %>' />
                        </EditItemTemplate>
                         <ItemTemplate> 
                             <telerik:RadColorPicker id="RadColorPicker1" runat="server" ShowIcon="true" /> 
                         </ItemTemplate>
                    </telerik:GridTemplateColumn>
                </Columns>
            </MasterTableView>
            <ClientSettings>
                <Selecting AllowRowSelect="true" />
                <Scrolling AllowScroll="True" UseStaticHeaders="True" />
            </ClientSettings>
        </telerik:RadGrid>

        <telerik:RadButton ID="btnGo" runat="server" Text="Go"  />

C#:

 protected void Page_Load(object sender, EventArgs e)
    {
        if (!this.IsPostBack)
        {
            DataTable dataTable = new DataTable();
            dataTable.Columns.Add("UserId", typeof(long));
            dataTable.Columns.Add("UserName", typeof(string));
            dataTable.Columns.Add("HexCode", typeof(string));

            dataTable.Rows.Add(1, "Bob", "#2E8B57");
            dataTable.Rows.Add(2, "Tim", "#BA55D3");
            dataTable.Rows.Add(3, "Jim", "#FF8C00");
            dataTable.Rows.Add(4, "Rob", "#4682B4");
            dataTable.Rows.Add(5, "Dan", "#B22222");

            grdUser.DataSource = dataTable;
            grdUser.DataBind();

        else
        {
            foreach (Telerik.Web.UI.GridDataItem user in grdUser.SelectedItems)
            {
                // Read new color values from the grid.
                string alteredColor = grdUser.MasterTableView.DataKeyValues[user.ItemIndex]["HexCode"].ToString();
            }
        }
    }

    protected void grdUser_ItemDataBound(object sender, GridItemEventArgs e)
    {
        GridDataItem item = e.Item as GridDataItem;

        if (item != null)
        {
            RadColorPicker rcpDeviceColour = e.Item.FindControl("RadColorPicker1") as RadColorPicker;

            if (rcpDeviceColour != null)
            {
                string hexCode = item.GetDataKeyValue("HexCode").ToString();
                rcpDeviceColour.SelectedColor = System.Drawing.ColorTranslator.FromHtml(hexCode);
            }
        }
    }

How do I read the updated color values in the grid during a postback?

Thanks in advance,

"Check All" feature is not working as expected with Load On Demand

My current version - Telerik.Web.UI, Version=2021.1.330.45

I am using RadComboBox control and property EnableCheckAllItemsCheckBox="true". Therefore "Check All" feature enabled.

And other properties are as below

EnableLoadOnDemand = true;
ShowToggleImage = true;
ShowDropDownOnTextboxClick = true;
ShowMoreResultsBox = true;
ItemsPerRequest = 10;
EnableVirtualScrolling = true;

steps are as follows.

1. check "Check All" checkbox. Then first loaded 10 records got checked.

2. Then loaded another set of items clicking arrow icon at the bottom of the record list.

3. Loaded next 10 records and now all together showing 20 records. At this stage all checkboxes are unchecked but still "Check All" checkbox is checked.

4. Unchecked "Check All" check box and and checked again. Now it is checked only last loaded 10 records only instead of 20 records.

I tried to resolve this by following code. But not luck.
