Forms Data Controls :: Gridview Not Passing Parameters To SQL Data Source?
Feb 13, 2011
I have a gridview and I have an edit template for one control. I have a drop down box in this edit template so that you can select a value from it and then when you hit 'Update' the value from the drop down box is committed to the updated record. Unfortunately when I do hit the update button I get a fault that the "Status" field cannot be null.
Here is the code that picks the value from the drop down value and assigns it to the new values list:

I have added a gridview in my aspx web page. I have added a hyperlink field, to navigate to another page from the gridview. I am getting the error as:
"There was an error rendering the control.
Index(zero based) must be greater than or equal to zero and less than the size of the argument list. "
This is the code i have used:
[Code]....
[Code]....
When i remove the hyperlink, the grid is getting displayed. I know, there is something wrong i have coded in the DataNavigateURLformatstring, but not sure what is wrong.
I want to pass the StudentID,CourseID,ChildImageID with the link as the querystring.

I Have a gridview where I have a link to a details page and I need to pass multiple parameters. I currently have the following:
<Columns>
<asp:BoundField DataField="AssocID" HeaderText="AssocID" InsertVisible="False"
ReadOnly="True" SortExpression="AssocID" />
<asp:BoundField DataField="FirstName" HeaderText="First Name"
SortExpression="FirstName" />
<asp:BoundField DataField="MiddleInitial" HeaderText="M. I."
SortExpression="MiddleInitial" />
<asp:BoundField DataField="LastName" HeaderText="Last Name"
SortExpression="LastName" />
<asp:BoundField DataField="State" HeaderText="State" SortExpression="State" />
<asp:BoundField DataField="EMail1" HeaderText="EMail 1"
SortExpression="EMail1" />
<asp:BoundField DataField="AddrType" HeaderText="Addr Type"
SortExpression="AddrType" />
<asp:HyperLinkField DataNavigateUrlFields="AddrID,AssocID"
DataNavigateUrlFormatString="Details.aspx?AddrID={0}&AssocID={1}" HeaderText="Details"
Text="Details" />
<asp:BoundField DataField="AddrID" HeaderText="AddrID" InsertVisible="False"
ReadOnly="True" SortExpression="AddrID" Visible="False" />
</Columns>
According to all I have read my DataNavagateUrlFields string should work but it isn't. The deal is that any one (AssocID) can have multiple AddrID's associated with it. Regardless of which I choose I only get back the first AddrID for that AssocId.

SELECT
reg_code, pc_serial, act_code
FROM user_reg
WHERE reg_code=@reg_code
I want to pass parameters to the other Stored procedure when the edit button is clicked in order to update the 2 columns in the specific row at the time. I now how to pass parameters in a regular btn click event or function, but in the case of edit btn in grid view I don't know how to capture data from specific row and then pass it to the SP. Here is Stored Procedure to update the columns (every user always has the same reg code, but may have more than one serial number and activation code, I want to let the user update serial number and then based on the serial number generate new activation code in the SP.):

I'm using the DetailView control to display employee details from a specfic company, but it seems when I try to create the query in the data source wizard I'm unable to select the variable for the WHERE clause, only the web pages control components.
The employees are selected through the company name which is entered at the beginning of the page and in turn is used to select the company id.

I have a ListView displaying data from Table A using a SqlDataSource.
I want to take the displayed data (and these are just the standard columns representing fields in Table A) and store them in Table B using a Stored Procedure
(The scenario is much more complex but I've left out anything not relating to this exact problem).
I've added a Button to the ListViews ItemTemplate and I'm using OnItemCommand to create a Sub for its "Click" in the Code Behind.
This is a simplified chunk of the SQL I'm using to insert the ListView's fields into Table B using the Stored Procedure "InsertCart":
[Code]....
Where I've highlighted "Description" in the last line. In a GridView, this would be enough. Description is a Column name in Table A and B and iy's an Item in the ListView. But I'm realising that, with ListView's, the data binding is not as "automatic" as a GridView. Just using the columnname is not enough.
What do I use instead of the word Description to reference this column in the Parameter?

I know how to pass parameters to Reportviewer in LocalReport mode via textboxes on the page where the user enters them and then they click refresh and everything works fine. What I cannot figure out is how to not pass parameters and make the report display everything, which should be the default.
I know I am missing something really obvious on the Report Parameters screen. Does anybody know the secret?

I am currently writing an ASP .NET (Framework 3.5) page that has a Grid View inside it.
One of the columns of this GridView contains only buttons, that if clicked should open a popup dialog.
To open the dialog I wrote the following code on the button's event handler:
[Code]....
Now when I click on any of the buttons the dialog opens just fine, however I need to pass some parameters to the dialog so that they can be displayed inside it. That's why I've encoded a Base 64 string and passed it as an argument of the popup dialog (apparently if I just used the plain string, the dialog would not open because the string contained linefeed characters).
Unfortunately I wasn't able to get the parameter (base 64 string) on the code behind of the popup dialog. How can I do this?

From: Dropdownlist1.selected value To: (CustomerID)

From: txtTitle (Title) To: (Title)

The btnAdd event is suppose to calls:

Below is my code for both the page and class. Although my class is expecting parameters, I don't know how to get the parameters to the insert function in my class.

I'm using a GridView to output some information regarding an account, specifically account balances. Problem is, if there is no balance linked to the account, I need for the grid to simply display 0 for each column. EmptyDataText isn't sufficient as the columns still need to be listed, but just have the value 0.
After researching it seems like I will need to add a dummy row to the gridview if it is empty, but how do I do this using C# and ASP? Quick note as well, not sure if it's relevant but the grid will only ever contain one row.

I have a gridview in a user control which I'm using to display a list of items. The data source is a list of objects (not using ObjectDataSource). I have paging enabled on my gridView. The trouble is that I am forced to rebind my grid in my paging method, otherwise the grid loses all it's data when a user clicks a page button. Is there a good way of binding to an enumerable list such that the values are reused on postback?
[Code]....
protected void gridView_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
BindGrid(); //Not Good. Removing gives me an empty grid.
((GridView)sender).PageIndex = e.NewPageIndex;
((GridView)sender).DataBind();
}

I'm sure it was discussed hundred of times, but maybe this time will elucidate some new points )
The question is: do I need to limit number of selected rows in data source for GridView?
When I use paging in GridView does limiting selected rows make GridView work faster?
Now I use ObjectDataSource with Linq in functions.
[Code]....
Does this make sense or I can just use LinqDataSource without thinking of selected rows?

Is it possible to use dynamic query filters with a gridview using a stored procedure as a data source? What I'm thinking of is a search page where there are multiple controls to enter in a search string and a radio button for the AND/OR query filters between the various controls. If not, what would be the best way to allow a user to select an AND / OR with a group of different query controls?
Here is the page I have created thus far using a view and no AND/OR option. I but I can't get it to work with my SP, also listed below:
