I keep getting a null reference when I try to access a listbox inside the EditItemTemplate of a formview. I check the mode before accessing the control (Formview1.CurrentMode) to make sure it is in edit mode and even set it manually to edit mode again! But formview1.findcontrol("blah") returns null. Formview1.EditItemTemplate does not have a FindControl method, not sure what else to try.

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've been searching in all the forums, and websites for the last 4 hours without finding a solution for a problem that in the beginning I tought it was an easy one!!!This is my problem, I have a gridview with the following colums: select (link), Room Type (for hotels), and TotalThe total field Is a template field it has in the custom binding property a function: find_total(Eval("Room")) this function makes some calculation and returns the calculated Total value, and shows in the gridview without problems,The thing I cant do is: when the user clicks on the select link I want to get the text of the template field and put in a label control.
I tried, almost all the events of the datagrid, to reference the content of my template field but sometimes I receive a null value (seems that Im looking for the value before the find_total function has been executed) or I get an error "the index is out of range".I dont know how to approach this, I tought It has to be much easier, but Im very confused right now, if anybody knows how to do this

I need to generate a gridview with dynamic columns, on each cell I need a button that inserts-deletes a relationship in a database. The relationship is of course between what is represented by each column and row. I decided to use a gridview and create templatefields which I add programmatically to the table. I successfully got to that point but when i decided to raise a click event from the buttons or a rowcommand from the gridview I could not do it. I´m looking into doing this with button fields right now but I´m curious on how this can be accomplished?

In a page, there is a lable called lblTotal and a gridview with 3 columns; Name, Percentage and Amount.
Name and Percent are values that come from a database. Next I need the caluclate the Amount field. The Amount field should be set by taking the Percentage column value in each row, against the value in lblTotal and displayed in the Amount column
So for example
If the value in lblTotal is £200 and the dataset in my gridview looks like this...
Name......Percent......Amount
John......20%..........
Dave......60%..........
Mark......20%..........
Then the result would be this
Name......Percent......Amount
John......20%..........£40
Dave......60%..........£120
Mark......20%..........£40
So I guess I would need to do this using OnRowCreated and do a find control maybe?
i have a gridview as follows,
<asp:GridView runat="server" ID="gvPO" AutoGenerateColumns="False" >
<Columns>
<asp:TemplateField HeaderText="PO No."><ItemTemplate>
<asp:LinkButton ID="lnkPo" runat="server" Text='<%#Eval("Purchase_order_no") %>' ></asp:LinkButton>
</ItemTemplate></asp:TemplateField>
</Columns>

The linbutton shows Purchase_order_no. When i clicked on a paricular purchase_order_no., it will navigate to another page with a gridview that shows details of that particular Purchase_order_no...

I have a gridview, whose columns I am dynamically binding. There are two fixed columns, one is a button field and another is a template field containing an image. The other columns might vary in number and behaviour, so before binding the grid, I am removing all columns of the gridview except the button field and the template field. But after doing this, if i try to do a findcontrol for the template field(Image column), it is notgetting the control. Means while removing the other columns, this image control also getting removed.Below is my code:
[Code]....
Now, after this i call the databind method. The problem is with the for loop, where I am removing the columns after the image column. And I am not able to find the control after that.In rowdatabound i am trying to find the control like this:

I am using an IComparer to do the sorting of the gridview and binding it to a list of objects. It used to be that the linkbutton in the first template field was being done like this:
[Code]....
The sorting worked just fine when it was like this, but I would prefer not to use a querystring value. The problem with using the linkbutton is that the sorting appears to work (there are only two rows in my test case and they change places), but when the linkbutton is clicked on it is in the same order before the sort took place. After each sort the gridview's datasource is reset to the newly sorted list of objects and the databind method is called.
I have a gridview and basically at page load I want it to display with an empty row. The first field in the gridview would be a template field containing a textbox. I wan't to be able to type in, for example, a product code ('abc'). This would be the parameter for the stored procedure and then the rest of the columns (40+ additional columns) in the gridview would populate with the rest of the data pertaining to that product code (i.e. price, unit of measure, etc.). In short the template field texbox is the control to bind the gridview.
After the row is populated I could click a button or link that would add that entire row to my gridview and then add another empty row where I could enter another product code... populate the row then add that row to the gridview. and so on...
I have a GridView that is bound to a DataTable containing questions. Each question has a possible score of 1 to 9 which is handled by a Template Field with a RadioButtonList databound to another DataTable (containing the values 1 to 9). This all works fine except as an added complication, some of the questions have an extra choice in another field. So the problem is how do I bind the second Template Field to a datasource that is dependent on the question. It's like passing a parameter to the datasource of the second Template Field, the value of the parameter being the Key Field of the particular row. Is this possible and if so, how do I do it
