El hyperlink hlPlus es un campo de hyperlink dentro del campo de plantilla de GridView (Plantilla de artículo).

Answer 1

Lo hice accediendo a los controles dentro del control de la celda. Encontrar en todas las colecciones de control.

 ControlCollection cc = (ControlCollection)e.Row.Controls[1].Controls;
Label lbCod = (Label)cc[1];

Answer 2

Prueba esto:

foreach(GridViewRow row in GridView1.Rows) {
if(row.RowType == DataControlRowType.DataRow) {
HyperLink myHyperLink = row.FindControl("myHyperLinkID") as HyperLink;
}
}

Si está manejando el evento RowDataBound, es así:

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if(e.Row.RowType == DataControlRowType.DataRow)
{
HyperLink myHyperLink = e.Row.FindControl("myHyperLinkID") as HyperLink;
}
}

Answer 3

Puede usar este código para encontrar HyperLink en GridView. Uso de e.Row.Cells[0].Controls[0] para encontrar la primera posición de control en GridView.

protected void AspGrid_RowDataBound(object sender, GridViewRowEventArgs e)
{
if(e.Row.RowType == DataControlRowType.DataRow)
{
DataRowView v = (DataRowView)e.Row.DataItem;
if (e.Row.Cells.Count > 0 && e.Row.Cells[0] != null && e.Row.Cells[0].Controls.Count > 0)
{
HyperLink link = e.Row.Cells[0].Controls[0] as HyperLink;
if (link != null)
{
link.Text = "Edit";
}
}
}
}

Answer 4

Si su GridView es databond, haga una columna de índice en el conjunto de resultados que recupera de esta manera:

select row_number() over(order by YourIdentityColumn asc)-1 as RowIndex, * from YourTable where [Expresion]

En el control de comando que desea usar, haga que el valor de la propiedad CommandArgument sea igual al índice de fila de la tabla DataSet RowIndex, de esta manera:

<asp:LinkButton ID="lbnMsgSubj" runat="server" Text=''<%# Eval("MsgSubj") %>'' Font-Underline="false" CommandArgument=''<%#Eval("RowIndex") %>'' />

Use el evento OnRowCommand para disparar al hacer clic en el botón de enlace de esta manera:

<asp:GridView ID="gvwStuMsgBoard" runat="server" AutoGenerateColumns="false" GridLines="Horizontal" BorderColor="Transparent" Width="100%" OnRowCommand="gvwStuMsgBoard_RowCommand">

Finalmente, el código detrás de ti puede hacer lo que quieras cuando el evento se desencadene así:

protected void gvwStuMsgBoard_RowCommand(object sender, GridViewCommandEventArgs e)
{
Panel pnlMsgBody = (Panel)gvwStuMsgBoard.Rows[Convert.ToInt32(e.CommandArgument)].FindControl("pnlMsgBody");
if(pnlMsgBody.Visible == false)
{
pnlMsgBody.Visible = true;
}
else
{
pnlMsgBody.Visible = false;
}
}

Answer 5

protected void gvTurnos_RowDataBound(object sender, GridViewRowEventArgs e)
{
try
{
if (e.Row.RowType == DataControlRowType.EmptyDataRow)
{
LinkButton btn = (LinkButton)e.Row.FindControl("btnAgregarVacio");
if (btn != null)
{
btn.Visible = rbFiltroEstatusCampus.SelectedValue == "1" ? true : false;
}
}
}
catch (Exception ex)
{
throw ex;
}
}

textboxID= ctl00$MainContent$grd$ctl12$ctl00;
