I have a problem that is most likely easy but I'm missing something small.
I have looked at numerous entries on Stack Overflow with the same question but I must be doing something wrong.
I am trying to get the value of a textbox in a GridView after typing into it. I want to take that value and update a SQL field.
Here is my GridView:
<asp:GridView ID="ASPxGridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="SALESID" HeaderStyle-HorizontalAlign="CENTER" HorizontalAlign="CENTER" CellPadding="4" ForeColor="#333333" GridLines="Both" AllowSorting="true" AllowPaging="true" PageSize="100" OnRowDataBound="ASPxGridView1_RowDataBound" OnSorting="ASPxGridView1_Sorting" OnRowUpdating="ASPxGridView1_RowUpdating">

Here is my gridview _RowUpdating method:
protected void ASPxGridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
Debug.WriteLine("row updating");
int index = Convert.ToInt32(e.RowIndex);
Debug.WriteLine("Index: " + index);
GridViewRow selectedRow = ASPxGridView1.Rows[index];
TableCell itemIDSelected = selectedRow.Cells[1];
TableCell rowPRD = selectedRow.Cells[11];
TableCell rowShipToday = selectedRow.Cells[12];
TableCell rowNotes = selectedRow.Cells[13];
string itemIdSelectedText = itemIDSelected.Text;
string rowPRDSelected = rowPRD.Text;
string rowShipTodaySelected = rowShipToday.Text;
string test = ((TextBox)selectedRow.FindControl("NOTES")).Text;
string test1 = ((TextBox)ASPxGridView1.Rows[index].FindControl("NOTES")).Text;
TextBox test2 = ASPxGridView1.Rows[index].FindControl("NOTES") as TextBox;
string test2text = test2.Text;
//string rowNotesSelected = rowNotes.Text;
//Debug.WriteLine(itemIdSelectedText);
//Debug.WriteLine(itemIdSelectedText);
//Debug.WriteLine(rowPRDSelected);
//Debug.WriteLine(rowShipTodaySelected);
Debug.WriteLine(test1);
Debug.WriteLine(test);
Debug.WriteLine(test2text);
//Debug.WriteLine(selectedRow.Cells[0].Text);
//Debug.WriteLine(selectedRow.Cells[1].Text);
//Debug.WriteLine(selectedRow.Cells[2].Text);
//Debug.WriteLine(selectedRow.Cells[3].Text);
//Debug.WriteLine(selectedRow.Cells[4].Text);
//Debug.WriteLine(selectedRow.Cells[5].Text);
//Debug.WriteLine(selectedRow.Cells[6].Text);
//Debug.WriteLine(selectedRow.Cells[7].Text);
//Debug.WriteLine(selectedRow.Cells[8].Text);
//Debug.WriteLine(selectedRow.Cells[9].Text);
//Debug.WriteLine(selectedRow.Cells[10].Text);
Debug.WriteLine(selectedRow.Cells[11].Text);
//Debug.WriteLine(selectedRow.Cells[12].Text);
//Debug.WriteLine(selectedRow.Cells[13].Text);
Debug.WriteLine("-----------");
//Debug.WriteLine(rowShipTodaySelected);
//Debug.WriteLine(rowNotesSelected);
}
When I run this and I type something in, the debug writeline's show.
I know i'm on the correct line because the index is correct per the line I am clicking the Update button on.
Sample debug output from above looks like this:
row updating
Index: 5
D31948P01
PRD-00030521
PRD-00030521
I cannot seem to get the value of the NOTES TextBox field. As you can see with my testing I've tried using a FindControl and I've tried having it as a TextBox and also trying to get it directly to a string.
I've set breakpoints and each time I do it the test
variable is null
. I'm missing something and I do not know what.
To summarize: On non-text fields I can pull the data from the field. On TextBox fields I cannot even using the FindControl method.
What I want to do: Get the TextBox field value in the GridView so I can update the database.
StackOverflow links I've tried before asking this question:
c# Get value (text) of a bound textbox in a gridview
How to get value of TextBox of GridView in C#?
Manipulate textbox on gridview C#
Get TextBox value from GridView cell
ASP.net C# Gridview ButtonField onclick event
Thanks in advance. I've spent over 6 hours of attempting this without results. I don't understand it well enough yet. If there are any tutorials or videos explaining GridView's please let me know what they are so I can understand better.
The reason why RowUpdating method cannot find the text inside the textbox is most likely because of the postback. Clicking update button causes a post back to server. Before ASPxGridView1_RowUpdating is called, there is an a call to re-build the gridview ie.: ASPxGridView1.DataBind() . To avoid this, wrap the databind in an if (.Page.IsPostBack)
Below is a basic working example
<asp:GridView ID="ASPxGridView1"
runat="server"
AutoGenerateColumns="False"
OnRowUpdating="ASPxGridView1_RowUpdating">
<Columns>
<asp:TemplateField HeaderText="NOTES" >
<ItemTemplate>
<asp:TextBox ID="NOTES" runat="server" TextMode="MultiLine"></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
<asp:ButtonField ButtonType="Button" HeaderText="" CommandName="Update" Text="Update" />
</Columns>
</asp:GridView>
Code behind:
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
// This code will not be reached if you click update button.
var data = new string[] { "a", "b", "c" };
ASPxGridView1.DataSource = data;
ASPxGridView1.DataBind();
}
}
protected void ASPxGridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
int index = Convert.ToInt32(e.RowIndex);
GridViewRow selectedRow = ASPxGridView1.Rows[index];
TextBox txtNotes = (TextBox)selectedRow.FindControl("NOTES");
Debug.WriteLine(txtNotes.Text);
}
