Rad Gridview get cell value, delete row and restrict duplicate values in textbox

Hi,
I have successfully added three controls in radgridview, Textbox,Combobox and button in winform page load.
Here the code i used.

        Dim grdTextBox As New GridViewTextBoxColumn
        grdTextBox.Width = 140
        grdTextBox.FieldName = "Index Name"
        RadGridView1.Columns.Add(grdTextBox)


        Dim comboColumn As New GridViewComboBoxColumn("Type")
        comboColumn.DataSource = New [String]() {"Text", "Number", "Deciaml", "Notes", "Date", "Option"}
        comboColumn.FieldName = "Type"
        comboColumn.Width = 200
        RadGridView1.Columns.Add(comboColumn)
      

        Dim btn As New GridViewCommandColumn
        btn.Image = My.Resources.close
        btn.Width = 25
        RadGridView1.Columns.Add(btn)

After i click and add values inside gird view, i want to manipulate values in grid view like check duplicate value, remove row and get values for store in database.

1.How to restrict duplicate entry in textbox ?
2.How to delete row using button ?
3.Is it possible to add running number which is not visible in interface and used for delete row. ?

Pls replay asap in vb language.

Regards
Aravind

Using a Callout as a Tooltip with an Embedded Label TextBox

I have a textbox with an embedded label and use a callout like a tooltip. I saw your code from https://www.telerik.com/forums/using-callout-as-a-tooltip.

The process works fine when using a plain textbox but clicking in the eltextbox to select becomes an issue because the focused control keeps changing between the embedded label and the callout. Is there a way to implement these two controls together? Constant clicking in the ELTextbox will eventually get it selected.

Attached is a sample project.

Thanks,

_Dave

Is there an event that is triggered when the READONLY flag is set on this control (or any other control in fact)?

Thanks in advanced.

Keytips are not working for Radpageviewpage

Hi Team,

I have tried setting the keytips for radpageviewpage using the property,

radpageviewpage.item.keytip="C"

But while running the application, I don't see any keytips enabled after pressing on Alt key. Only tooltips (letters are underlined) are working to access the pages by holding the Alt key + Letter that has underline.

Here I am attaching my sample code, please find attachment.

RadTextBox: BackColor is displayed incorrect/transparent in 2023.1.314.40 version.

Hi Team,

We are using RadTextBox the version is Telerik.WinControls.UI.dll -> 2023.1.314.40. And setting the backcolor is 'System.Drawing.SystemColors.Control' but its showing screen transparent color(gray- this is not correct).

Example code block: Its applied > 1000 places in our project.

this.txtTagNo.BackColor = System.Drawing.SystemColors.Control;

We are planning to migrate 2023.1.314.40 version with visual studio 2022.

Please refer the attached screenshot. Could you please help on this issue?

Note: Its working fine in Telerik.WinControls.UI.dll -> 2013.3.1127.40 with Visual Studio 2010

Thanks
