I'm using the code below to extract data from a gridview and populate it into textboxes for the days and two drop downs for Project and Category.
For some rows in the gridview everything but the category ddl populates correctly. If I click the row a second time the category ddl displays the correct category.
why I have to click twice for some rows? And how do I fix this?

I have a link button that I want to function as delete. I have to do it this way because I want confirmation before allowing deletes. In my debugger, I flagged this block of code and run it line by line. For some odd reason, it thinks my selected row. Maybe I'm overlooking something? Here's my code behind source:

In expression web I changed this line from this WHERE [ID] = ?"> to this WHERE [ID] = date()"> and I get the right results.
GridViewDetails uses templatefields. In edittemplate I put a button called "ButtonUpdateAdjustAmount" with OnClick="Update_AdjustAmount" in the EditItemTemplate for the "Amt to be Adj" column. There is also a textbox. My user's should be able to edit the textbox, but I also want the ability to click the button and the textbox populated with the correct calculated value. The formula varies based on the "code" column which is a dropdownlist called "DropListCode".
I am fairly new to asp.net, vb, etc...so forgive my code writing. Eventually I need to also put the same functionality on the insertrow for my gridview. But first wanted to get the edit one working. I am using templatefields for all columns and the FooterTemplate to perform the Insert New Detail Line.
I can get the functionality to work for the first data row and only if I take out the If code.SelectedValue = ... line and leave 1 static formula. However that isn't going to work. If DropListCode.SelectedValue is DNR then AdjAmt should be ((q_ordered - q_received) * cost). If DropListCode. SelectedValue is OV then AdjAmt should be (RKNumber * cost). If DropListCode.SelectedValue is NB the AdjAmt should be ((q_received - q_ordered) * cost). If DropListCode.SelectedValue is DAM then AdjAmt should be (RKNumber * cost)

i have two grid views
gridview1 has check box[a1] and one value[a](in total two columns) with objectdatasource1 for datareferencing from database
another gridview2 has to select only the selected/checked value of gridview1 of checkbox1
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>"

and now as you can see i have a link Button and i have its handler. Before i used to have a Check box and i could find with row has been selected, but now my style is different , i want to get value of "lblOrderID" for the selected record. I dont use a Checkbox to get the selected item because i dont allow multi select into functionality.
How can i get that on the server or client side.
I have to GridViews, say grd1 and grd2.
grd1 is bound programmaticaly in Page_Load, it contains hyperlink column that loads the same page with ID value in request.
grd2 also is bound in Page_Load and it depands on ID from request (so, after grd1 is clicked grd2 loads data).So, actually grd2 depands on grd1.
After page is reloaded with id in request, I should know the row from grd1 where user has clicked and display some of column data seperatly (say in label lblColumnData). How to know which row was clicked?

I would like to create a gridview that gets data from a datasource but doesn't display it in the normal fashion based on my table layout.
Example:
Table layout is:
Name Emp# Dept# Booking Code# AccessId
This is how it looks in the gridview but I would like it to look like:
Name: John Doe Dept#: 12
Booking Code#: 1234 Booking Code#: 67
AccessId: 33
What data object will give this?Gridview won't work I think.
