I am unable to access the data in the gridview's selected row. I have done this lots of times but must be forgetting something.
Here is my gridview:

I'm trying to keep these questions seperate for people searching after me, .
I have the following code on SelectedIndexChange of GridView1
[Code]....
I have a drop down list that you can choose values from, and depending on which item you pick GridView1 changes, this all works correctly, and if I select one of he rows the SelectedIndex changes. My problem occurs when you choose a different value from the drop down list, GridView1 Changes accordingly, and by default a record is selected. But selectedindexchange is never fired again until I manually select another record from the gridview which is a problem.
i am still stumped with this operation: i am trying to retrieve a GridView selected row data..here is my code.. the commented part that gives me the selectedindex works just fine....but the one giving the selected row cell value does't work and there is no error.. The update operation is done successfully...weired. i need to assigned selected row cells values to variables ..do some calculations and then re-assign the result calculation to cell[9]..
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
string s = GridView1.SelectedRow.Cells[5].Text;
TextBox1.Text = s.ToString();
//string s2 = GridView1.SelectedIndex.ToString();
//TextBox1.Text = s2.ToString();
}
I have seen a lot of things on the net on this but nothing seems to work. I have a GridView with name and other information on files stored in a database but also on a Server. I display the gridview with the files and the user selects the file to delete (row) by hitting the command field for Delete. I have an event on the gridview for code behind. Here I want to access the file name for the row selected, to be able to include it in the File.Delete statement.
Even before this I want to display the selected file name in a label back to the web page. I have tried everything including findcontrol selectedValue, etc. Nothing is working. I either get complier error, or nothing is displayed in label. If I let it go the the File.Delete step I get access error becasue there is no file name. HELP. here is screen shot of the gridview. Ignore the download button for now. That is my next headache to figure out. So based on the screen shot I want the value of log_doc from the gridview. It is in a column called file_name
File ID
File Name

I have my data table generated dynamically binded to grid view. (Autogeneratecolumns true)
in my UI its displaying the column headers.
am not able to access it by grdname.HeaderRow.Cells[0].Text
am not able to get the names from the columns also.
since am binding the columns dynamically i am not able to get access to all the columns
and am able to get only 2 columns which i have mentioned in my aspx which are the command buttons edit and delete.
am trying to access all these in Gridview_RowCommand event. need to get the value in the (dynamic) column named Id for the row on which the edit or delete button is clicked. since it doesnt have a header am unable to access it bcoz i dont know the index of the cell too..
I am having a problem with using A Gridview SectedIndex or value in a sql ControlParameter. When I select the row it does what I need it to except it shows that there is no data.
but if I add Default Value of 1 the data shows up, but it needs to read from the Gridview.
[Code]....
I even added sqlDataSource.DataBind() in the SelectedIndexChanged Event to see if that would fix it but - No! I used it with a DropDown and it worked only when I use AutoPostBack = true of course.
I have parent gridview5 and nested child gridview6 within it. The page is working as expected and formatted as i need it now.. I added a select button to the child gridview6 and when i click on it i get an error: {"Object reference not set to an instance of an object."}
I found examples of using the find control, but within the parent gridview.. and i use that fine with other controls.. but cant figure out the right combination of finding the selected row for the nested gridview so that i can display a modalpopup.
I want to select a row in my GridView based on a known data key value at runtime.
In other words, I have a data key value, 2 for ex., and the primary key value of one of the rows in my GridView is 2. How can select that row? (Without having to go through each row to find which one matches my key, then setting the SelectedIndex.
i have gride view and there are three dropDownList in every row in grideview,i want get selected value from every DropDownList,and pass the values to storeprocedure in sql,I dont know how pass value every row, to store procedure,and StoreProcedure get 3 value.
View 1 RepliesI have a gridview in one UpdatePanel and a FormView in another UpdatePanel.
The FormView UpdatePanel refresh is triggered when the GridView SelectedIndexChanged event fires. This then displays the FormView. However when a user navigates to another page in the GridView or sorts the data then the GridView is refreshed and the SelectedIndex
is changed to nothing in the code behind via the GridView DataBinding event.
The FormView UpdatePanel does not refresh to reflect this. I have to manually set the FormView datasource to null and update the FormView UpdatePanel in the code behind.
My question is why doesn't my FormView UpdatePanel update when the SelectedIndex of the GridView is altered in the code behind.

how to update the text within a textbox inside the same cell of a DropDownExtender and ListBox while the option the user clicks on inside the ListBox
Here is a code snip of the template field

Then I also have this on the RowDataBound event of the gridview

What I don't understand on how to do is tell which row the onclick event took place and in what column. Then I also need to figure out how to build the JS for the front end to handle this and update the proper rows / columns textbox
I'm trying to populate a detailsview according to the selected row in a gridview. How do you choose what the selectedindex is? For example my sql statement is:
SELECT [Assignment_ID], [Staff_ID], [Client_ID], [Day], [Month], [Year], [Start_Time], [Job_Type], [Billable_Time], [Travel_Time], [KM_Travelled], [NC_Time], [SP_Time], [Billed], [Description] FROM [Assignment] WHERE ([Assignment_ID] = @Assignment_ID)
and @ assignment_ID is gridview.selectedindex
but when it runs I get the error:
Input string was not in a correct format.
Description:
An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.FormatException: Input string was not in a correct format.

I have been researching this issue for a couple of days and have found a lot written about it, but none of what I have found has fixed the problem I am having.
I work for a school system, and my principals are wanting to take a list of the staff members at their school and create staff lists for different activities they perform. I thought I would load the staff into Gridveiw1, and when they select a record have it move over into Gridview2 and "delete" from Gridview1.
I am loading my full staff into a datatable (SQL Server backend), and setting this datatable as my gridview1 datasource. At this point, it loads great, and cosmetically speaking sorts and pages fine. The problem occurs in the codebehind after a Sort or Page change has occurred -- when I select a record and move it over into Gridview2, it is moving the original record that was at that postion on Page 1 instead of the sorted or "new page" record.
So if the initial list comes in as:
Teacher 1
Teacher 2
Teacher 3
The sort button is hit so that the list now starts out like:
Teacher 7
Teacher 13
Teacher 5
If they select "Teacher 13" to be moved over after the sort, instead it is still moving over "Teacher 2" -- the initial teacher in that index before the sort.
The Gridview setup on my aspx page looks like this:

I display a GridView where ther user can choose a Datarow with the select action. I catch the selection with the "SelectedIndexChanged" event of the GridView.

My problem is I can't use the SelectedIndex to identify the Access Row because when the user uses paging/sorting the SelectedIndex is not the AccessRow. Somehow I have to identify the selected row the user chooses with the PrimaryKey in Access ("Number").

I have a gridview with dropdown boxes. As soon as the complete gridview is databound, I want to loop through ALL the rows and set the values of the dropdown boxe in a row based on the value of another column in the same row. The gridview is databound, all data shows up. The condition "If ddl.Items(j).Value = searchstring Then" evaluates as true, but somehow the selected item in the dropdownbox is NOT changed and remains "<ignore>"
