Hi Maher Khalil,

Thank you for contacting us.

To achieve your task you need to add a GridViewCommandColumn to the RadGridView:

GridViewCommandColumn commandColumn = new GridViewCommandColumn("Search");
commandColumn.UseDefaultText = true;
commandColumn.DefaultText = "Search";
this.radGridView1.Columns.Add(commandColumn);

Then you need to handle the CommandCellClick event, so you can show the search dialog you need and update the RadGridView row:

void radGridView1_CommandCellClick(object sender, EventArgs e)
{
    OpenFileDialog dialog = new OpenFileDialog();
    DialogResult result = dialog.ShowDialog();

    if (result == DialogResult.OK)
    {
        string selectedFileName = dialog.FileName;

        this.radGridView1.CurrentRow.Cells[0].Value = selectedFileName;
    }
}

I hope it helps. Please write back if you have further questions.

Good afternoon,

in my project I have a button inside a gridvew that clicking opens a form.

This form is what I fill in two columns of the grid.

wanted to know how I program the button to open the form.


My code:

 



//Preenche template registos

templateRegistar.AllowAddNewRow = false;

templateRegistar.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;

templateRegistar.Caption = "Registo de Lavagem de Fardamento";

templateRegistar.Columns.Add(new GridViewTextBoxColumn {
HeaderText = "Nº Ticket", FieldName =
"SYS_Registo_Entrega.SYS_Ticket.Ticket_ID", IsVisible = true });

templateRegistar.Columns.Add(new GridViewTextBoxColumn {
HeaderText = "Fardamento", FieldName =
"Fardamento_Funcionario.Fardamento.Descricao", IsVisible = true });

templateRegistar.Columns.Add(new GridViewTextBoxColumn {
HeaderText = "Quantidade", FieldName = "Quantidade", IsVisible = true
});

templateRegistar.Columns.Add(new GridViewTextBoxColumn {
HeaderText = "Utilizador", FieldName =
"SYS_Utilizador.Funcionario.Nome_Funcionario", IsVisible = true });

templateRegistar.Columns.Add(new GridViewTextBoxColumn {
HeaderText = "Data Entrega", FieldName = "DtEntrega", IsVisible = true
});

templateRegistar.Columns.Add(new GridViewComboBoxColumn {
HeaderText = "Utilizador", FieldName = "Utilizador_IDLevantamento",
IsVisible = true });

templateRegistar.Columns.Add(new GridViewComboBoxColumn {
HeaderText = "Data Levantamento", FieldName = "DtLevantamento",
IsVisible = true });

templateRegistar.Columns.Add(new GridViewCommandColumn {
HeaderText = "", DefaultText = "Registar Levantamento", UseDefaultText =
true, MaxWidth = 150, Name = "Levantamento" });

templateRegistar.Columns.Add(new GridViewTextBoxColumn {
HeaderText = "Num_Mecanografico_Funcionario", FieldName =
"Num_Mecanografico_Funcionario", IsVisible = false });

 



GridViewRelation relationRegistar = new GridViewRelation(radGridViewFuncionarios.MasterTemplate);

relationRegistar.ChildTemplate = templateRegistar;

relationRegistar.RelationName = "FuncionarioLavagem";

relationRegistar.ParentColumnNames.Add("Num_Mecanografico_Funcionario");

relationRegistar.ChildColumnNames.Add("Num_Mecanografico_Funcionario");

radGridViewFuncionarios.Relations.Add(relationRegistar);

 

radGridViewFuncionarios.CommandCellClick += radGridViewFuncionarios_CommandCellClick;

//Botao registar Levantamento

void radGridViewFuncionarios_CommandCellClick1(object sender, EventArgs e)

{



GridCommandCellElement click = (GridCommandCellElement)sender;

SYS_Registo_Entrega row = click.RowInfo.DataBoundItem as SYS_Registo_Entrega;

RegistarLevantamento reg = new RegistarLevantamento(row);

if (reg.ShowDialog() == DialogResult.OK)

{

PreencheFuncionarios(); // se foi adicionado novo funcionario a BD, entao atualiza a lista

}

 



}

Hello Cristiana,

Thank you for writing.

According to the provided code snippet, it seems that you use hierarchical RadGridView with GridViewCommandColumn in the child template. As you have already found out, the CommandCellClick event is the appropriate event to detect clicking over the command cell. In the event handler you can open another form, using the ShowDialog method. In the form's constructor you can pass the clicked data bound object and visualize it in the new form in order to perform some changes for example. Please find attached a sample project, demonstrating this behavior. I am not sure if it is the exact requirement. If it is not, please specify in details what is specific case. It would be better if you open a new thread and provide a sample project with the very specific case. Thank you in advance.

I hope this information helps. Should you have further questions, I would be glad to help.
