Can the select command of a SqlDataSource be given by code in the code behind file. Also by calling the SqlDataSource.Select can the select statement be executed?
View 3 RepliesI want to bind an ObjectDataSource to a property in my asp page and I want to do it in the page's aspx code, not in code-behind. I've already done it in code-behind, as follows:
[Code]....
I'd prefer to get rid of the ugly code-behind and just do this in mark-up. Something like
[Code]....
This gives me a run-time error: Cannot create an object of type 'System.Object' from its string representation 'SelectedBook' for the 'DataSource' property.Is there a way of doing this declaratively and not in code-behind? Further, what if what I want is to actually use a child property of the property in question? For example, if my Book object has a ReaderComments collection, can I databind to it decaratively in the aspx mark-up?
I need to pass the control parameter to Sql Datasource in code behind,

I have a datagrid which is fetching data from my ASSETS table. The MaintenanceID field is linked to the MaintenanceID in the MAINTENANCE table. This also contains the MaintenanceValue (Yes or No). I have followed a tutorial so that in edit mode the dropdownlist in the gridview selects between Yes or No. This then passes through the value of MaintenanceID (but displays the MaintenanceValue).
I now want it so when i click update..instead of showing meaningless MaintenanceID (1 or 2) it shows the value (No or Yes). When I change it, it seems to mess up the drop down list and all kinds of things. I'll attach my current code - I think its a simple fix but as soon as I sort it - relationships and stuff go tits up! Datasource1 is populating the gird. Datasource2 is populating the dropdownlist template in the edit template.

View 2 RepliesI have a SQLDataSource that I'm having a little trouble with. I am using a parameterized FilterExpression and am not getting something right. So, I want to see what the final SELECT output will be that the SQLDataSource is generating and will be sending to the database so I can see what the SQL looks like. How do I do this?
Added:
Here is my code so far:
DetailSource.SelectCommand = "SELECT * from Pictures ";
DetailSource.FilterExpression="ParID = '{0}' AND CardNum = '{1}' AND SeqNum = '{2}'";
DetailSource.FilterParameters.Clear();
DetailSource.FilterParameters.Add("ParID", GridView1.SelectedRow.Cells[1].Text);
DetailSource.FilterParameters.Add("CardNum", GridView1.SelectedRow.Cells[2].Text);
DetailSource.FilterParameters.Add("SeqNum", GridView1.SelectedRow.Cells[3].Text);
Response.Write(DetailSource.ToString());

I have a gridview with insert new row controls in the footer binded to sql datasource. I want to show the footer when the datasource is empty. Although the empty data template is there but any other solution you fellows can tell me ?
View 7 RepliesI am trying to populate a gridview using two tables. I also have a strongly typed dataset and used the method on this page: [URL] the problem is that, when i try to use two table the gridview does show up (I checked through debugging that the datatable comes back as empty).
View 2 RepliesSince I was not able to figure out my previous problem I decided to go ahead and make my own update statements and change the update command on a datasource I have. So I have a few textboxes and whatnot that allow you to change data and then click an update button. When I click that update button the page seems to refresh as if it was updating the record but the data in the boxes reverts back to what it was. I also created a ONUpdated sub and the label text change does not show.

View 8 RepliesI am using the SQLDataReader to execute a Stored Procedure that accepts two parameters (BuildingTID and Department) to return the appropritae Value in my case The Director of the Department. My problem is I get the following error when I run the code that I added below for review. Let me also add that the user is selecting the values that I am using for the stored procedure from 2 DropDownLists. I am getting it when I try to assign the value that is in the Department DropDown
list to the first parameter.
Dim myParm As SqlParameter = getDirectorsCMD.Parameters.Add("@BuildingTID", SqlDbType.Int, 15).Value = (ddlDepartment.SelectedValue)
Also obviously there are more issues with my code than just the error because the datareader records property is false meaning I am not returning a row
