Forms Data Controls :: Failed to convert parameter value from a DataControlFieldCell to a String - GridView Error?
I am using VS2008 with asp.net 3.5 and enterprise library 4.1. I am getting the following error when I try to connect to database.
"Failed to convert parameter value from a SqlParameter to a String"
Here is my code
[code]....
data.MakeInParam(
"@DOB",SqlDbType.DateTime,10,cust.DateOfBirth),
im new to .net, reponse grt intput for me to get in to it.
I swear I'm overthinking this as I've tried different combinations to do an insert from Code Behind to my Sql DB.
This is what my table looks like:
[Code]....
My code behind:
[Code]....
I suspect that the problem may be my date. The format that goes from the UI is mm/dd/yyyy.
I am trying to get the 'userid' of the logged in user using the code below:
"MembershipUser myObject = Membership.GetUser();
String userId = myObject.ProviderUserKey.ToString();"
and later using it as a parameter to the stored procedure.
The logic here is, the user should login first in order to retrieve his/her album. when the user is logged in, im retrieving the 'userid' and using it as parameter to load the corresponding album from the database.
when i login and open the albumpage, im end up with this exception:
"Failed to convert parameter value from a String to a Guid".
What could be the reason and how can i avoid this exception.
by the way im using the aspnet_Users table's userid field.
When running our web application the following message appears:
Failed to convert parameter value string to decimal. We believe that the problem might be with the sequence which generates the user_id. The user_id should be the output after successful insert of record. The stored procedure works well from within the DB and Visual Studio. Our DB version: 11gR1 on Windows.The web form has a button event with this c#-code:

I'm using a GridView control to edit data in a MySQL database.
I've created the C# code behind but I'm having trouble pulling back the parameter from a radiobutton control to populate an Int32 field in the database. I'm getting "Input string not in correct format"This is the particular bit (amongst a host of others of the same type) that is causing the problem:
cmd.Parameters.Add("?yes", OdbcType.Int).Value = (Convert.ToInt32(((RadioButton)GridView2.Rows[i].FindControl("edYes")).Text));
I have written a code to insert emp details into database and i am also inserting local date(i,e system date) into to the table to know/have an idea at what date the employee inserted details. I have set date format add/MM/yyyy and its working well in my local system, but after uploading the site into server (the server is shared server) iam getting error and the error message is Failed to convert parameter value from a String to a DateTime.
Surprisingly, it is working well in server when i chaged the date format to MM/dd/yyyy, but now its not working in my local system and getting the same error.
here is my code......where its throwing the error in storeimage.executenonquery() line that Failed to convert parameter type to st
if (newBmp != null)
{
Bitmap convBmp = AddTextToImage(newBmp, text);
Byte[] myimage=ImageToByteArray(convBmp);
//string type = myimage.GetType();
// String query = ;

I am not sure where my app is failing but most probably this is where it is failing.. I think lblExpID.Text is the culprit. Here's the relvant part of my code:
Dim lblExpID As Label
For Each item In LSGrid.Rows
lblExpID = item.FindControl("lblID")
If txtExpGenFund.Text <> "" Then
sqlArray(i) = ExpDetailsID & "," & (lblExpID.Text) & "," & MunID & "," & _
Val(txtExpGenFund.Text) & "," & Val(txtExpDetSpecialRevenue.Text) & "," & _
Val(txtExpDetCapitalProjects.Text) & "," & expTotal & "," & reportingYear & "," & "Test Comments" & "," & UserID
End If
Can u help me identify why i am getting this error looking at the sp below:

@ExpDetailsID int=0 output,

I'm developing a custom webcontrol from GridView.
I've run into this bizarre situation wherein I get the below error if I set page size other than 5 in the page using this control.
"Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request."
This GridView is a hierarchial type. I add a new GridView below each row in the webcontrol overriding OnRowDataBound.
If I set pagesize as 5 the paging works properly.
I am getting error "Cannot implicitly convert type 'string' to 'System.Data.DbType".
When I am passing Stored procedure parameter it expets 'System.Data.DbType" and the Data member is declared as a string.

I'm not sure what do I have to fix if I want to sort the columns.
If I bind the data manually what is the code for codebehind to allow sorting for particular columns.
