Show the selected row record in textbox/label

How do I make the selected row record from a DataGridView show in a TextBox? I got some TextBox and Label in a Form. I want the text inside the TextBox/Label to change when the user selects a row record from the DataGridView. I tried the following code to make it happen, but it doesn't work
private void ItemTable_RowHeaderMouseClick(object sender, DataGridViewCellMouseEventArgs e)
{
label_itemid_show.Text = ItemTable.Rows[e.RowIndex].Cells[0].Value.ToString();
text_itemname.Text = ItemTable.Rows[e.RowIndex].Cells[1].Value.ToString();
text_itemprice.Text = ItemTable.Rows[e.RowIndex].Cells[2].Value.ToString();
text_itemstock.Text = ItemTable.Rows[e.RowIndex].Cells[3].Value.ToString();
}

I'm working on a project that includes a features similar to yours. Currently I select a record in a datagridview and need to show it's values to textboxes so that any values can be edited.
This is how I tackle the problem.
Models.Item item = DAL.ItemDAL.GetItem(Convert.ToInt32(ItemDataGrid.CurrentRow.Cells[0].Value));
tbModifyItemID.Text = Convert.ToString(item.ItemID);
tbModifyItemName.Text = item.ItemName;
It's the ItemDataGridView.CurrentRow.Cells[0].Value that finds me the ItemID of the selected record.
In your case it's [DataGridName].CurrentRow.Cells[FieldNo, starting at 0].Value.ToString();
This allows you to click on any cell in the record and still retrieve the specified cell in the code.
Hope it helps c:
PS:
If you put it inside a
private void ItemDataGrid_SelectionChanged(object sender, EventArgs e)
method it will run the code anytime you click a different cell in the datagridview.

You can use the following:
lblDetails.Text = dgMainGrid.SelectedRows[0].Cells[1].Value.ToString();
lblDetails: A label on the form.
dgMainGrid: DataGrivView on the form.
PS: Just make sure you select the row inside the datagrid and not any particular cell, row selecting is done by clicking on the left of your first column i.e. the row selector column which gets added at the run time in WinForms.

C# gridview row onclick

I notice there is a "AutoGenerateSelectionButton" function but it's not really what I want. I want to be able to two things when a row is clicked (anywhere of the row):
change the color of that entire row.
get the value of a specific column and update another table accordingly.
How can I acheive that without writing client-side javascript functions?

Assuming this is a webform, you need to access SelectedIndexChanged event of the gridview using a codebehind file.
from here you can modify properties
protected void ChangedRow(object sender, EventArgs e)
{
this.GridView1.SelectedRow.BackColor = System.Drawing.Color.Red;
....
}

Highlight button if field is not null C#

I was hoping someone could share some code relative to "flagging" rows in a gridview. The first column of my gv is a column of buttons that bring up a new window based on the item listed in that row.
I would like to highlight the button (or the row in some other way) if one of two conditions (or both) is true.
The window pop-up that opens with the button click shows a small gv if data exists as well as a Comments formview. So I would highlight if that gv appears (meaning the data exists--query for this is already written) or if the Comments field is not null.
Little tricky since the two conditions work off different SPs and different source tables, but getting a highlight for at least one would still be a huge step.
Thank you so much for your help!

You can do it in the RowDataBound event of the Gridview. If a certain condition is met, then you can change the color of that row to distinguish it from other rows. For example:
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
DataRow dr = ((DataRowView)e.Row.DataItem).Row;
if(dr["ColumnName"] && dr["ColumnName1"])
{
e.Row.Style.Add("Color", "Red");
}
}
}

Command behind a GridView ButtonField

I got a question about the command behind a ButtonField (image type) in a GridView.
Got a GridView called gvIngevuld in wich I show rows of data and 1 ButtonField row.
Now I have to put code behind these buttons (Each of them the same) to put some things in PDF format.
The problem is I don't know how to put code behind these buttons ?
The code I have :
<asp:ButtonField ButtonType="Image" ImageUrl="~/Images/pdf.png" CommandName="pdf_click" />
As you can see I used the CommandName="pdf_click" property but when I click one of the buttons there's only a postback but nothing happens.
Anyone who can help me out here ?
in case needed, code behind :
protected void pdf_click(object sender, EventArgs e)
{
lblWelkom.Text = "Succes!";
}
Thanks.

You should use RowCommand event of gridview. Set the commandArgument to your item's unique key. (By default, it passes the row's index)
void gvIngevuld_RowCommand(Object sender, GridViewCommandEventArgs e)
{
// If multiple buttons are used in a GridView control, use the
// CommandName property to determine which button was clicked.
if(e.CommandName=="pdf_click")
{
// Convert the row index stored in the CommandArgument
// property to an Integer.
int index = Convert.ToInt32(e.CommandArgument);
// Retrieve the row that contains the button clicked
// by the user from the Rows collection.
GridViewRow row = gvIngevuld.Rows[index];
//gbIngevuld is your GridView's name
// Now you have access to the gridviewrow.
}
}
Also, If you have set the DataKeyNames of the gridview, you can access it as follows:
int index = Convert.ToInt32(e.CommandArgument);
int ServerID = Convert.ToInt32(GridView1.DataKeys[index].Value);

Just an addition, I wrote and tried exactly the same however the button still not working...
...it took some time till I realise that I forgot a thing, which was
OnRowCommand="<YourGridViewName>_RowCommand"
inside your GridView element in the **.cs* file

The CommandName property does not define the method to call. For that you need to create a method that is bound to the command event of the control.
I don't know too much about about GridViews i'm afraid but I would think the easiest way to do this would be to select it in design view in Visual Studio, go to properties, click on the events button (looks like a lightning flash) and double click on the RowCommand event propety. This should automatically create a method that is bound to a command button event.
You can then use the GridViewCommandEventArgs parameter to access the CommandName, CommandArgument and CommandSource properties to work out which buttom caused the event to fire.

Textbox control in DataGridView

I am working on a datagridview in C# in windows application. I want to add textbox controls in DataGridView. So, when we run it then textbox should be shown in gridview and we can put value in it and My grid has 3 columns and I want to add new row in grid when I press tab on 3rd column of gridview.
How do I do this?

It's hard to provide a precise answer since your question is lacking in detail and pretty general, but to get textboxes in your DataGridView, you're going to want to add some instances of DataGridViewTextBoxColumn to the DataGridView's Columns collection. This will cause them to be populated with textboxes in each row.
To detect when the user presses tab on the 3rd column, you can add a 1-2 pixel wide fourth column and detect that it has recieved focus (almost definitely from a tab keystroke) using the OnCellEnter event.
Good luck!

So, for the "display textboxes by default portion of your question, here's the skinny:
On GridView->Edit Columns, add the columns you want to use explicitly. Then click on the link "Convert this field into a templateField". This will let you tweak the generated HTML for those cells. Say OK. Then go to GridView->Edit Templates. For your favorite Column, copy the ItemEditTemplate into the ItemTemplate. (ItemTemplate is the default. ItemEditTemplate contains the properly bound edit control.) Now all of your data fields will default to "editable."
I'm guessing you have a submit button. You'll need to tell the GridView to update the rows on submit., like so:
For Each r As GridViewRow In GridView1.Rows
Dim mon = System.Int32.Parse(CType(r.FindControl("TextBox1"), TextBox).Text)
If mon <> 0 Then GridView1.UpdateRow(r.RowIndex, False)
Next
Obviously, you'll want different logic inside there, but the basic loop/findControl/updateRow logic should apply.
Microsoft has a walkthrough on this here: Performing Bulk Updates to Rows Bound to a GridView

Try this, for example if you want to set your first column in datagridview as a textbox control:
private void dtgrdview_CellClick(object sender, DataGridViewCellEventArgs e)
{
if (e.ColumnIndex == 0)
{
TextBox txtbox1=new TextBox();
dtgrdview.Controls.Add(txtbox1);
Rectangle rectangle = dtgrdview.GetCellDisplayRectangle(0, e.RowIndex, true);
txtbox1.Location = rectangle.Location;
txtbox1.Size = rectangle.Size;
txtbox1.TextChanged += txtbox1_TextChanged;
txtbox1.Leave += txtbox1_Leave;
txtbox1.Visible = true;
}
}
and don't forget to add this event in the same class as like below to call it when the cell have the focus:
private void txtbox1_Leave(object sender, EventArgs e)
{
txtbox1.Visible = false;
}
private void txtbox1_TextChanged(object sender, EventArgs e)
{
dtgrdview.CurrentCell.Value = txtbox1.Text;
}
