Forms Data Controls :: Pulling The Value Of A TemplateField From A GridView?
Nov 23, 2010
I have a GridView, bound to a table (Meals) in a SqlDataSource.
Into that GridView, I have added a TemplateField, which contains a DropDownList (which displays the numbers 1 - 10, added manually; no Data Binding). And, I've added a ButtonField.
When I click the Button, I want the values of some of the GridView rows PLUS whatever value was selected in the DropDownList to be pulled out and stored in a second Sql table (Orders).
Pulling the rows bound to the SqlDataSource is easy but JavaScript is needed (I think) to pull the SelectedValue from the DropDownList. I understand women more than understand JavaScript (that's how little I know) and the code below has been kindly offered by another forum user who is at a loss, himself, now.
Here's the code and the error message I'm getting.
ASPX:
[Code]....
And here's the Code Behind:
[Code]....
No design time errors reported but here's the run time error:
Object reference not set to an instance of an object.
On the following line:
Line 28: if (row.RowType == DataControlRowType.DataRow)

I'm trying to pull a value from a Gridview so that I can create a running subtotal. I've looked at a number of examples but they all seem to fail.
Why does this not work? Each and every reference I try to make to the cells "value", comes up null.
Sample code1:
[Code]....
Sample code2:
[Code]....
In sample code 2, I get the "header text" for the column...but I know the value in the cell...so it fails on a data conversion.

I have a templated control embedding a checkbox in a GridView I have an event on the checkbox which has a loop that pulls ALL of the checked checkboxes and the associated value. I only want to pull the datavalue of the checkbox that I just checked but the properties/methods associated with that checkbox event are not giving me any sort of index or item.value from which to do this.

I use a gridview with products, in which one column lists the manufacturer, and the next colum lists the item number.This gridview works fine, but now I want to add a product image on the same row. Instead of using a stored image location, I simply want to make a link to the image like this:
"www.mywebsite.com/images/manufacturer/itemnumber.jpg "where the manufacturer and the itemnumber are the same as displayed in that particular row in the manufacturer and itemnumber columns. I am not versed well enough (yet???) to reuse the data from those two columns.

I have dynamically created my gridview in the codebehind.
All is working correctly.
I now need to dynamically add a TemplateField to the gridview and populate it with a Button.
I have the following code so far:
TemplateField tempField = new TemplateField();
Button btnRemove = new Button();

I'm relatively new to the VS environment. I'm using VS2010 Beta 2 with VB. I have a Gridview setup to pull a list of employees. Next to their name I have edit and delete icons. When I leave the icons as ButtonFields, they pass the DataKey value to my code behind perfectly. When I convert the ButtonFields to TemplateFields, they no longer pass the DataKey.

Though it is usually not a big deal to edit the source code to accomplish this, I am just curious if there is an easier way to reverse the conversion of a column to a TemplateField. The covnersion can be done by a simple click. Is there a similar click to reverse it?

I have a gridview with a DropDownList (contained in a TemplateField). I have set the OnSelectedIndexChanged event to a function called "ddlAgent_SelectedIndexChanged" This allows me to aquire when a user has changed the value for the dropdownlist. What I need to do is persist this newly selected value to the database for the gridview record. The problem I'm having is how to I get the datakeyNames value for that row? See code below!
TemplateField source
<asp:TemplateField HeaderText="Agent">
<ItemTemplate>
<asp:DropDownList ID="ddlAgent" runat="server" AutoPostBack="False" OnSelectedIndexChanged="ddlAgent_SelectedIndexChanged">
</asp:DropDownList>
</ItemTemplate>
<ItemStyle HorizontalAlign="Center"></ItemStyle>
</asp:TemplateField>
ddlAgent_SelectedIndexChanged
Protected Sub ddlAgent_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs)
Dim gvItems As DropDownList = CType(sender, DropDownList)
' Write the selected Agent ID to the Inquiry record.
'Dim ID As Integer = gvMaint.DataKeyNames(e.SelectedIndex).Value ' THIS FAILS BECAUSE
e.SelectedIndex is not part of System.EventArgs
End Sub

I have one two GridViews on a page. One Gridview uses BoundFields inside of the GridView and the Update statement works just fine. The other GridView utilizes TemplateFields due to the fact that Validation Expressions have to be used. I also want This GridView to be able to update the vlues when the user clicks on the Update link on the right side of the GridView. The GridView that uses the BoundFields updates just fine, but the GridView that uses TemplateFields will not update. I have checked and everything is correct other than this difference of BoundField and TemplateField.

I binded user control in gridview dynamically using templatefield (through code behind)
User control consists of 2 textboxes and one dropdown.
There is one button outside the gridview on the form. On click of that button i have to save the values of usercontrol's (child controls i.e textbox and dropdown values) but i am not able to get the values of user controls.
I am able to get User Control using LoadControl and child controls using FindControl but not able get values i am getting textbox values as blank and dropdown value as 0th selected index even though there is value entered by the user.
