and I am getting texbox value in codebehind code.
protected void getTextBoxValue(object sender, EventArgs e)
{
DropDownList ddlfullname = (TrackerGrid.HeaderRow.FindControl("ddlfullName") as DropDownList);
string selectedValue = ddlfullname.SelectedItem.Text;
TextBox mobilenumber = (TrackerGrid.HeaderRow.FindControl("txtMobilenumber") as TextBox);
string mobile = mobilenumber.Text;
TextBox email = TrackerGrid.HeaderRow.FindControl("txtemail") as TextBox;
string emailid = email.Text;
TextBox staloc = TrackerGrid.HeaderRow.FindControl("txtStartDate") as TextBox;
string startlocatdate = staloc.Text;
TextBox endloc = TrackerGrid.HeaderRow.FindControl("txtEndDate") as TextBox;
string endlocadate = endloc.Text;
}
I am getting empty value when I debugging this code.I think my code is correct but how i am not getting value of textboxes, i don't understand. Please help me for solving my issue.
Thanks in advance.
You probably did not wrap the DataBind() of the Gridview inside an IspostBack check. If you do not then the values will be rested by the DataBind instead of being saved with ViewState.
protected void Page_Load(object sender, EventArgs e)
{
//not here
TrackerGrid.DataSource = source;
TrackerGrid.DataBind();
if (IsPostBack == false)
{
//but inside an ispostback check
TrackerGrid.DataSource = source;
TrackerGrid.DataBind();
}
}

I have wired a gridSearchResults_RowUpdating event for everytime an update link button is clicked. What I want to do is loop through the row at the event rowindex and add the textbox value in the row cell to a string collection. I am having troubh accessing the textbox in the cell. If this doesn't make sense my code should help make things clearer.

C#
protected void gridSearchResults_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
GridViewRow row = gridSearchResults.Rows[e.RowIndex];
foreach (gridviewrow c in gridSearchResults.Rows[e.RowIndex])
{
}
}
So does anyone know a good way of looping through the cells of a gridview row and grabbing the textbox value in the gridview row cell. Thanks
Try this:
foreach (TableCell cell in gv.Rows(e.RowIndex).Cells)
{
TextBox txt1 = (TextBox)cell.FindControl("txtControlName");
// or if you don't want to hard code the control name and assuming that there is only 1 control in the cell then use this:
TextBox txt2 = (TextBox)cell.Controls(0);
}
I have a regular gridview with insert,edit,update, delete operations as in below image:
Before inserting data to the DB, I am doing the validation on the textboxes if they are filled or empty like this:
if (txtNewID.Text == "")
{
string message = "Please enter ID";
ScriptManager.RegisterClientScriptBlock(Page, this.GetType(), "Alert", "alert('" + message + "')", true);
isValid = false;
}
But after clicking the OK button of the alert message, the values that i added in the required textboxes are getting lost. How to keep the values of the textboxes in gridview?

Whenever PostBack event is called then we can loss the page data.Did you place the grid in updatepanel otherwise place it in grid if you didn't get maintain the values in viewstate.

Bind the validator to the textbox you need to be required before a submit/post is valid using the ControlToValidate property.
Try to find required field validator dynamically on RowDataBoundEvent of Grid View.
TextBox tb=e.Row.FindControl("txtBox") as TextBox;
tb.ValidationGroup=e.RowIndex;
RequiredFieldvalidation rv=e.Row.FindControl("rv") as
RequiredFieldValidator; rv.ControlTovalidate=tb; rv.ErrorMessage;
rv.ErrorMessage="*";
rv.ValidationGroup=e.RowIndex;
I have label within a DetailsView.
I need to change Text property of this Label inside the DetailsView after event ItemInserted has been trigged.
Script does not throws any error, but the Label does not change its text property.
Any ideas what I am doing wrong?
Thanks for your time!

Code-behind:
protected void uxInsertAuthorInput_ItemInserted(object sender, DetailsViewInsertedEventArgs e)
{
String FirstName = e.Values["FirstName"].ToString();
String LastName = e.Values["LastName"].ToString();
uxMessageDisplayer.Text = string.Format("Author: {0} {1} has been added.", FirstName, LastName);
// problem is here:
Label myAllert = (Label)uxInsertAuthorInput.FindControl("uxAllert");
myAllert.Text = "TEST";
}
you need to use ItemUpdated event of detailsview rather than ItemInserted event
ItemUpdated: Occurs when an Update button within a DetailsView control is clicked, but after the update operation. from here
I am sure this will resolve issue 100%
