Index was out of range. Must be non-negative and less than the size of the collection. Parameter name:index. If I read this method correctly any time someone clicks on a cell in the dataGridView it should populate the textbox with the contents of the selected cell.
Edit: Unless you're trying to get a specific value within the row no matter which cell in the row is clicked In relation to why it's causing an issue when you click the header using your method that's because the header row is effectively row -1 of the dataGridView so e. RowIndex would give a value of -1 which doesn't exist within the dataGridView's dataSource. Edit: You'd think I could've put all that in one response, but noo I had to go and TEST stuff between hand lol.
The value being sent to the textbox is System. It doesn't work. While I don't specifically have a solution for this I did find this post elsewhere that gives some explanation of why it's happening and one person's description of how they worked around it.
Sorry : All out of ideas Apparently this affects the click event at the same time and causes your error. Short of creating separate click event handlers to handle the difference between header click and non-header click which I'm not sure where to start I don't know if there's a solution to match your needs. My form1 has a datagridview, which has a lastname and firstname column, and a button named 'EDIT'.
When I select a row in the datagrid and then click the button 'EDIT', my form will open which has two textboxes, wherein the selected row from my datagridview will pass the value. So I can edit the selected row in datagridview from form1 to form2 using the two textbox and update. Ok, you just went past the level of knowledge I can comfortably claim about dataGridView at pm while it's just starting to cool down from exceptionally overly hot out lol. Gonna stop guessing and looking up scenarios now and hopefully someone more familiar with dataGridView will be able to help.
I read that one way to fix the problem is to set the visibility of the header to false. But I really need the headers. I used this. Parameter name:index How to fix this? Maybe something like this instead? Hope this helps : Please mark as solved if your issue is resolved. As a side note this might work for your original code: if dataGridView1.
When clicking the column header, it shows the error. I'll keep looking but I've not really done a lot of dataGridView work in the past.
This is only the first step for what I really wanted. How could I do this?Last post Feb 02, AM by decker dong - msft. I have a column in datagridview which is display the vendor services.
It is a textbox type when display. However, when I want to edit the service. I would like to click on the cell, and the cell change to combobox for me to choose.
How can I do that? In the EditItemTemplate section have a dropdownlist in the edit section of it. First of all, thanks for your reply. I knew the way for web application, but I'm asking for window application's datagridview control. Doing so would make things slow to a crawl. The cell contains a Value which is rendered in the cell, and that's what the user sees. Now, when you start editing a cell a ComboBox control is created, or an existing one reused, and it is embedded in the cell.
The Value property of the cell itself is assigned to the SelectedValue property of this ComboBox control. Just like any normal ComboBox, if there is no matching value an exception will be thrown. What you would need to do would be to change that such that the DropDownStyle was set to DropDown and the editing control allow values other than what's in the list.
You could access the editing control itself from the outside, i. The "proper" way to do this would be to create your own custom types. You would have to inherit the DataGridViewComboBoxCell class, and probably the column too, and add your own custom functionality to support this behaviour. Print Share Twitter Facebook Email.
