why datagrid_SelectedIndexChanged doesn't work the first time

Question

I have a LinkButton added in one cell in the datagrid. At the first click on it the SelectedIndexChanged doesn't fire but at the second it does. What can be happening?

I must say that I changed the linkbutton now it's on the datagrid in design time not in execution time and now it works. Any way here is the code I used before (I put only what I think neccesary if u need ALL the code just say it please) The first time the execution doesn't enter into the function dgMuestras_SelectedIndexChanged. Now it works don't waste your time if you don't want now it's just a curiosity (for me) what could be happening. Thanx! private void dgMuestras_SelectedIndexChanged(object sender System.EventArgs e) { txbVersion.Text = dgMuestras.SelectedItem.Cells[4].Text; txbReferencia.Text = dgMuestras.SelectedItem.Cells[2].Text; txbnmaterial.Text = dgMuestras.SelectedItem.Cells[3].Text; txbFichero.Text = dgMuestras.SelectedItem.Cells[6].Text; txbResumen.Text = dgMuestras.SelectedItem.Cells[9].Text; ddlIdioma.SelectedValue = dgMuestras.SelectedItem.Cells[7].Text; ddlPeligrosidad.SelectedValue = dgMuestras.SelectedItem.Cells[8].Text; txbFecha.Text = dgMuestras.SelectedItem.Cells[5].Text; } private void Page_Load(object sender System.EventArgs e) { if (!this.IsPostBack) { this.lblUsuario.Text = BBDD.Usuario(User.Identity.Name); BBDD.loadDropDownList(ddlIdioma idioma ididioma sdescripcion); BBDD.loadDropDownList(ddlPeligrosidad peligrosidad idpeligrosidad sdescripcion); } btnSalir.CausesValidation = btnNuevo.CausesValidation = btnCancelar.CausesValidation = btnBuscar.CausesValidation = false; if (dgMuestras.Visible) { arreglaGrid(); arreglaDades(); } } private void arreglaDades(){ for (int i=1; i<dgMuestras.Items.Count; i++) { Label lblIdioma = new Label(); Label lblPeligro = new Label(); lblIdioma.Text = ddlIdioma.Items.FindByValue(dgMuestras.Items[i].Cells[7].Text).Text; lblPeligro.Text = ddlPeligrosidad.Items.FindByValue(dgMuestras.Items[i].Cells[8].Text).Text; dgMuestras.Items[i].Cells[7].Controls.Clear(); dgMuestras.Items[i].Cells[7].Controls.AddAt(0 lblIdioma); dgMuestras.Items[i].Cells[8].Controls.Clear(); dgMuestras.Items[i].Cells[8].Controls.AddAt(0 lblPeligro); } } private void arreglaGrid() { dgMuestras.Items[0].Font.Size=1; dgMuestras.Items[0].BackColor=Color.FromName(#fc6500); for (int i=1; i<dgMuestras.Items.Count; i++) { LinkButton Hyp1 = new LinkButton(); Hyp1.Text = dgMuestras.Items[i].Cells[1].Text; Hyp1.CommandName = Select; Hyp1.CausesValidation = false; dgMuestras.Items[i].Cells[1].Controls.Clear(); dgMuestras.Items[i].Cells[1].Controls.AddAt(0 Hyp1); } }

I've had the same problem and if it's caused by the same error in the code I can't say since I don't see your code. Show us the code and we can help :-)
