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.
You can get better understanding thorough the below image of GridView, as:
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'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 Select button at the end of each row in gridview. I also have a separate button that I want to use to update one of the column of the selected row. This column contains a checkbox, I want to put a check in it when I click the button.
I do not want to use an Update button inside the gridview because I do not want the user to be able to change any other column.
Can anyone help? I have been researching this for a while now.
You've got a lot of option regarding your problem..
You could use Gridview's RowCreated or RowDataBound events or even on the buttons onclick event if that button is on the same row of the gridview(just get the sender etc//based on your logic).
here are some code snippet
If
e.Row.RowType = DataControlRowType.DataRow Then
e.Row.Attributes.Add("onclick", Page.ClientScript.GetPostBackEventReference(sender,
"Select$" & e.Row.RowIndex.ToString))
End If
My GridView is loaded with data from my database in a DataSet, which corresponds to Labels inside the GridView.
When users click the Select button on a GridViewRow, the button fills a TextBox outside the GridView from the selected row's column value.
After editing values in the TextBox outside my GridView, the user can click a button to move the new value from the TextBox back to the GridView (but not to the database).
My problem is: when I select the next row and do the same action, it clear the previous newly-added row data. It doesn't retain the previous row data.
I know it can be done by ViewState or Session, but it didn't work for me.
check for if(! ispostback) before filling data back to your grid. i am assuming that on click of select (Edit) button your page post back and then it fills value in textbox for edit and same time its refilling data in grid control also. so before filling value in grid control make sure its not postback.
