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.

I have a DataGridView populated from a list of objects. The DataGridViewis set to use fullrowselect with multiselect off.
I have a button above the table that they can use to select the next row. I have a Checkbox above the table that they use to change data in one of the cells of the selected row. The button and the Checkbox both work independently without issue.
I'd like to make it so that when they check that Checkbox it changes the data in the selected row cell and then selects the next row in the table.
No matter how I go about this, I either get the reentrant call error immediately or when I later try to select that row again.
I have tried BeginInvoke, BackGroundWorker, using a timer to change the row selection, setting a variable to remember the row and changing the value after the row selection has changed or after the row has validated. Every attempt gives me the same error.
My code is much too long to post here, but I may be able to create a simple app to demonstrate the issue if needed.
Please help.
Here is the code:
private void chkDone_CheckedChanged(object sender, EventArgs e)
{
ProcedureCode proc = getCode(gridCodes.SelectedRows[0].Cells[3].Value + "");
proc.done = chkDone.Checked;
setPnlProgress();
if(chkDone.Checked)
{
btnNext_Click(sender, e);
}
}
private void btnNext_Click(object sender, EventArgs e)
{
int cRow = gridCodes.SelectedRows[0].Index;
if (cRow < gridCodes.RowCount - 1)
{
gridCodes.CurrentCell = gridCodes[0, cRow + 1];
}
}
Here is a screenshot of the table and checkbox:Click to see screenshot
The second checkbox labled Done is the one that changes the value in the cell of the selected row. The third circle button selects the next row.
I found that the the checkbox CheckChanged event was being fired when I went to the next row as well as when the user clicked the checkbox. I added a flag to skip any action during the row entering phase and this resolved the reentrant error.
I've been trying to create Mp3 list using DataGridView to show info. I want to add data at runtime and I have Columns like Artist, Song Name, Rating, Path... but I want to be able to select entire Row when selecting a Cell. I've used this code for that:
private void DataViewGrid1_MouseClick(object sender, MouseEventArgs e)
{
int rindex = DataViewGrid1.CurrentCell.RowIndex;
DataViewGrid1.Rows[rindex].Selected = true;
}
and it works but the problem is that it's to sloooow! When I click on the cell whole row is selected but it's visually terrible. I can see cell selected and after a delay whole row is selected but the delay is just too long. Is there a faster (or better) way to do this? Or maybe there is a better control that can do this? I also want to be able to present rows in a different font (for example: change font color for the same artist in the list).
I'm open for all suggestions.
Thanks!
DataViewGrid1.SelectionMode = DataGridViewSelectionMode.FullRowSelect;
The entire row will be selected by clicking its row's header or a cell contained in that row.
If you want to color based on having a value in the cell, something like this will do the trick.
I am developing a windows form application where I am trying to edit data of selected row in a Datagridview using textbox and combobox (dropdown) in windows form application. There is a column called status in Datagridview whose value is text (e.g. status = "start"). I need to change the prepopulate combobox depanding on the status column of selected row in the Datagridview.
I am getting null value in selectedvalue of combobox
combobox1.SelectedValue = dataGridView1.Rows[rowIndex].Cells["Status"].Value.ToString();
Where
dataGridView1.Rows[rowIndex].Cells["Status"].Value.ToString() = "Start"
Is there a way to change the selected combobox option depanding on text instead of value in windows form application using C#?
If I'm understanding your question correctly, you have two columns inside a DataGridView: one containing text and one containing combo boxes, and you want the selected combo box element to change with the text.
I can't be overly specific because you haven't posted any code, but to get you started, you'll probably want to listen for a change in the text box column using an event handler:
myDataGridView.CellClick += myDataGridView_CellClick;
...
void myDataGridView_CellClick(object sender, DataGridViewCellEventArgs e)
{
if (e.ColumnIndex != TEXTBOX_COLUMN_ID) return;
object value = myDataGridView[e.ColumnIndex, e.RowIndex].Value;
}
The local variable value will then have whatever was entered into the textbox column. From there, you'll need to find the dropdown box in the same row (using e.RowIndex) and adjust its value however you wish.
On the "CellClick" event, maybe you should feed in the row into a DataGridViewRow object, then say if that cell within the row selected contains "Start", run a function that populates the combobox?
ex:
DataGridViewRow row = dataGridView1.Rows[rowIndex];
if (row.Cells["Status"].Value.ToString() == "Start")
{
//fill combobox with needed information
}
I have a GridView with many rows.
When a User click the EDIT button in GridView I need to retrieve a Control in that specific row (now in edit mode).
This Logic should work on GridEvent _RowUpdating
At the moment my code (wrong) look inside every Row, so the Control founded is not unique and I receive an error.
// Event handler
protected void uxManageSponsoredContentsDisplayer_RowUpdating(object sender, GridViewUpdateEventArgs e)
// My code (Wrong!!!!):
foreach (GridViewRow row in uxManageSponsoredContentsDisplayer.Rows)
{
TextBox uxStartDate = (TextBox)row.FindControl("uxEffectiveStartDateInput");
}
Hope my question is clear. Any idea how to do it? Thanks
Solution:
TextBox uxStartDate = (TextBox)uxManageSponsoredContentsDisplayer.Rows[e.RowIndex].FindControl("uxEffectiveStartDateInput");
You need to use the GridViewUpdateEventArgs e as it contains index of row being updated.
Use something like
uxManageSponsoredContentsDisplayer.Rows[e.RowIndex].FindControl("uxEffectiveStartDateInput")
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;
}
