How can I select a row clicking anywhere on that row in gridview? Which gridview event would suit it?
There is no ready-to-use feature. But this guy explains how to do it.
You basically have to extend the DataGrid class and add the event RowClicked to it.

I'm working with DataGridView in C#. I fill it with a table from database using BindingSource. After filling the DataGridView I need to add a row of checkboxes that should be first in the table, to enable data filtering in future.
I mean: for example after clicking "Load" button I get DataGridView filled with 4 columns of data and the first row should consists of checkboxes.
I confused. I use
DataGridViewCheckBoxCell checkCell = new DataGridViewCheckBoxCell();
SourceDGV.Rows.Add(checkCell);
I mean here:
But after clicking load button it says You can't add rows to databounded DataGridView
Sorry if ecxeption translated wrong, I translated it from Ukrainian.
Any help appreciated.
Am afraid, there is no concept of whole rows to be of some type(checkbox in your case) in DataGridView. It is other way around. You can have whole column to be of checkbox type. You'd use DataGridViewCheckBoxColumn for that.
Showing checkboxes in whole row even makes no sense for me: Assume you have data bounded Person object to the DataGridView. So there will be columns like Name, Age, Address. Now, on what basis you show checkbox in the row? How can a Name be converted to a bool(which is what checkbox needs as a value)?
One workaround I can think of would be, handle custom painting, If First row paint checkboxes over there and manually handle their click events. But am pretty sure it's not gonna be easy.
I have a winform application and after load a data on the gridview, I like to edit some of the cells and click a button. Once button click I like to see the changes on the RichTextBox. How can I do that. Is it possible?
I don't quite understand the 2nd part of your question, but you can read the cellvalue of a gridview with
GridView1.Rows[rowIndex].Cells[cellIndex].Value
Have a look at DataGridView.CellValueChanged Event
The DataGridViewCellEventArgs will give you row and column index that has been updated.
How does one turn a Gridview Row clickable which open a modalpopup in C#?
I have a gridview with several columns. Each row (the entire width of the row) needs to be clickable which onclick opens a modalpopupextender displaying a popup panal with detailed info on the row.
I have the modalpopupextender & panal working properly when an ImageButton is clicked. However I am removing the ImageButton and replacing its functionality with the row onClick.
I appreciate your time!
You should change the SelectionMode property to FullRowSelect.
You could use the SelectionChanged event to determine the current row selected.
GridView.SelectedRows[0].Index
will give you the index of the selected row. You will have to be sure MultiSelect is disabled as well.
So you have the index of the row selected, so now open whatever form needs opened depending on this index

I have a gridview with two extra buttons as Edit and Add on each row and I have a click event on each Edit and Add Linkbuttons through which I am opening a ModelViewExtender Dialog. I want when I am clicking on these linkbuttons on each row of gridview, all row data should accessed means Row Data of particular column (cells)from the row of clicked Edit link.

Please suggest me any solution regarding the same.
Thanks in advance.
You have tow ways, either you use the AutoGenereateEdit property to true which will generate these hyperlinks. then on the row editing event you can get all these values easily by using the "e.NewEditIndex" which is the rowIndex of the GridViewRow your editing.
The second way is that you have put these hyperlinks "edit" and "add" as templates, in order to access them you need to parse the the sender object to it's control on the hyperlink click event and then get it's parent which will return the GridViewRow that the control on, which will allow you to get all the values you want from that row like this:
//Debug it and just make sure that tow parents return the GridViewRow
GridViewRow row = (GridViewRow)(((HyperLink)(sender)).Parent.Parent);
I am fairly new to ASP.NET. I have a GridView control which has many rows. Based on selection of each row I need to enable/disable few list and text controls on the collapsible panel in a ASCX.
The issue I am facing is whenever I select any row the GridView sets the focus on the first row all the time due to postback.
How do I set the focus on the selected row?
Can I use GetPostBackClientHyperlink in the RowDataBound somehow to register a client-side script?
Reply with some code is much appreciated.
Add a handler to the SelectedIndexChanged event of your GridView and insert the following code into this handler:
GridView1.SelectedRow.Focus(); // where GridView1 is the name of your GridView
You can also use jQuery. I added a <div> with an ID that is only shown when a row is using the edit template.
$('#hiddenDIV').focus();
