I have a gridview and the gridview contains some boundfield, templatefield, checkbox and an update command button.
When I click the update button, I want to update only 2 columns. So I made rest of columns readonly=true.
BUT, there is a template field and I am changing the value of the template field from code behind. like below
[Code]....
I do not want to update the above column. so when I click update button, the rows having value more than 0 is working fine.
BUT The rows displaying "Expired" (value less than 0) showing error. It says "Object reference not set to an instance of an object."
Setting up the editItem template of a gridview. I have a template field with a dropdown list for editing. When the gridview goes into edit mode the dropdown list is displayed with all the right options but the current value of the field (pre-editing) is not the selected value of the dropdown list? How do I make that happen? I have a couple fields where the editItem template will use a dropdown list and I'm sure a user will not realize those values have changed and they will just edit what they intended to edit and save the changes, inadvertently also making changes to other fields.

View 3 RepliesI have 3 buttons that change the Information being displayed in my Gridview (Previous, Today, Forward). Now management wants to SUM the Date's information by column, I have figured out how to do this by changing the BoundField to a TemplateField and then add a FooterTemplate with a SQL DataSource. When I Press either the Previous or Forward button the data does not change in my Sum'd Footer column.

I have a grid view, that when bound, if the UserID isn't the same as the ID of the person who added a meeting, that I don't want to let that person edit or delete the meeting. (Since they didn't add it, they can't edit/delete it)
I have my gridview set up with template fields, and can determine if the UserID matches, but I can't figure out how to disable or hide this first column in the gridview for a specific row.

I have seen a number of posts on this, but none that quite serve my needs. I have a GridView with template fields. I use postback because when a value is entered in one field a calculation is done to supply the value in another field. I simply loop through all the rows after each postback (there are not many so it is fast). I do not use a select command or button to select a row. After postback I do not know how to return the focus to the row that was being used. I can return the focus to the first row just by using gridview1.focus.

View 5 RepliesI have a gridview that can be sorted by a few of the columns.
How do I tell the gridview to go back to the unsorted mode. That is, go back to listing rows in the order they appear in the datasource.
It's ok if this will only work the next time a rebind is done on the grid. Currently it's maintaining the sort mode after a rebind. I don't want it to do that.

View 2 RepliesI have a dropdownlist as a template item in a gridview - it populates fine and with the right values. I have an SelectedIndexChanged on the dropdownlist, and has set it for postback. In the SelectedIndexChanged event, I would like to know where the control that fired this event is, - which row in the gridview is it in? How do I get this info? If the row was selected it would be easy, but the only thing that has happened in that row is that the dropdown has changed value and consequently the SelectedIndexChanged event has been fired - is that enough to know which row the event has been fired from?
