How to get a Gridview label value inside Static method.

first of all DO not use static.

second use a repeater ( if you are using asp.net).

here is an exampl of the databound.

protected void AdditionalDevice_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Item)
{
var accessDevice = (WcfAccessDevice)e.Item.DataItem;
var additionalDeviceDropDownList = (DropDownList)e.Item.FindControl("additionalDeviceDropDownList");
var lblDeviceType = (Label)e.Item.FindControl("lblDeviceType");
var linePort = (Label)e.Item.FindControl("LinePortLabel");
var macRegularExpressionValidator = (RegularExpressionValidator)e.Item.FindControl("MacRegularExpressionValidator");
//Set error message
macRegularExpressionValidator.ValidationExpression = CompleetApplication.ValidatorInvalidMacAddress;
macRegularExpressionValidator.ErrorMessage = CompleetApplication.ValidatorInvalidMacAddressMessage;
// get the value of the current user device
var currentUserDevice = hfCurrentUserDevice.Value;
// Set the two labels
lblDeviceType.Text = accessDevice.DeviceLevel;
linePort.Text = accessDevice.LinePort;
additionalDeviceDropDownList.Items.Add(new ListItem
{
Text = accessDevice.DeviceName,
Value = accessDevice.MacAddress,
Selected = currentUserDevice == accessDevice.DeviceLevel
});
}
}

and the code for the itemcommand.

protected void AdditionalDevice_ItemCommand(object source, RepeaterCommandEventArgs e)
{
// set all your asp controls (label, ddl, textbox.etc)
DropDownList ddlAdditionalDevicesEdit;
try
{
var submitError = "";
switch (e.CommandName)
{
case "Edit":
// hide labels
var label = (Label)e.Item.FindControl("lblDeviceType");
var portLineLabel = (Label) e.Item.FindControl("LinePortLabel");
label.Visible = false;
portLineLabel.Visible = false;
var additionalDeviceDropDownListFromRepeater = (DropDownList)e.Item.FindControl("additionalDeviceDropDownList");
additionalDeviceDropDownListFromRepeater.Items.Clear();
for (var i = 0; i < additionalDeviceDropDownList.Items.Count; i++)
{
var item = additionalDeviceDropDownList.Items[i];
additionalDeviceDropDownListFromRepeater.Items.Add(item);
}
// show ddl
additionalDeviceDropDownListFromRepeater.Visible = true;
// show textbox

Mangesh G9y ago
To Access the Multiple Values of the label U must write that in Row_Edit or Row_updating command

dont think u will be able to get the values of particular label Unless U have only One row

You cannot access the controls in the Static Method

for that U need to do have the context of the page then do the find control an then u can do the Rest

May be u can do something Like this but better U should use the Jquery for the same
if (HttpContext.Current != null) { Page page = (Page)HttpContext.Current.Handler; TextBox TextBox1 = (TextBox)page.FindControl("TextBox1"); TextBox TextBox2 = (TextBox)page.FindControl("TextBox2"); }
