In My Project We Filter Dataview Which Contail Integer and string value
sort data likes this
dvv.RowFilter = filterfor + " Like " + SearchExpression;
but when integer value is encounter Error occurredÂ
Cannot perform 'like' operation on system.int64 and system.string
I am filtering dataview using my Date Column but the result is not proper because the Field value also stores time, so I want to convert this Date Field to only Date during Filter. How can I achieve this? Here is my code. And the actual value I am getting in the Dataset Field "CreationDate" is a DateTime field which is like
2010-01-21 14:35:25.203
2010-01-22 12:55:18.033
2010-01-26 12:10:06.990
But I only want to neglet time value and want to compare Date only.

I suspect that the problem may be my date. The format that goes from the UI is mm/dd/yyyy.
I was wondering if it is possible to assign 2 variables to DataView.RowFilter. if it is, how do I code it.

How to convert string value to int32.
In timsplit i have value "17:00 - 2:00".Then i am converting it TimeIn and TimeOut.TimeIn is string now and how to convert it to int32.I am getting error while convertin
Timesplit = strResultData.Split('-');
string TimeIn = Timesplit[0];
string TimeOut = Timesplit[1];
int TimeI = Int32.Parse(TimeIn);
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 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:

I am working with MVC2 and one of the view model's properties is IDictionary<Int32, String>.
This is not to be changed on the view. But when the form is posted back I would like to still get those values.
Can Html.Hidden store this property values?
How should I do this so the model still gets the IDictionary<Int32, String> values on the POST action?
I want to generate an overview for the user where he can see all columns in a table.Format is like:
columname | comlumntypecode | columntypename
Where I'm assuming that a column of type int must have some sort of typecode, e.g. 7
For example:
firstname | 4 | nvarchar(30)
lastname | 4 | nvarchar(50)
birthdate | 5 | datetime
uuid | 9 | uniqueidentifier
What is the SQL to get such a result?

This is in the codebehind of a page containing a gridview. The gridview has been customized to include two hidden fields hfsearchtext and hfsort that are used to search my database table and return results to the gridview through the use of a DataView.
As I'm new to this type of construct, can someone walk me through the code above? I receive an error message stating that the Value of System.Web.UI.DataSourceSelectArguments cannot be converted to an integer. How to rectify this error?
Sometimes Convert.ToInt32(object) will work and other times (Int32)object will work. How do you know which to use? I usually try one and if it doesn't work use the other but I'm sure that's not the best approach.

I have a dataview on a page. I am binding a list of Items, and each item has a Person object. So I get this exception "field not found in selected datasource" when I try to bind to any property on the person object.

It appears that the dataview is having problems with the person object because it will display all the properties for the Item correctly.
why I get a not found on the boundfield and not on the eval?
I have one gridview and i want to take all the values in a datatable or dataview.
I tried like this
DataTable gridTable = (DataTable) dataGrid1.DataSource;
but gridTable is showing null, it should not show null because gridview has lot of records with 3 columns
Is there any way i can convert/store a gridview.Datasource records in a datatable or dataview?
My web application calls a stored procedure and stores the result in a .NET datatable. I'd like to use this datatable and join it with other tables in my database. Is this possible?
Would the best way to set this up be to create another datatable and then use a dataview to join both datatables?

View 3 RepliesI have the following query:
[Code]....
The results look like this:
DocumentNumber NIIN QtyReq AvailBalance
12345 015551212 2 5
12346 015551212 1 5
12347 015551212 3 5
12348 015554787 10 12
As you can see, the first 3 documents are for the same NIIN, and their total QtyReq is 6, however there are only 5 Available for this NIIN.
I need a way to remove the document 12346 because it cannot be filled, the other 2 document can though. I cannot figure this one out, but it seems like it should be pretty easy.I am using MS SQL Server 200

I want to be able to store strings in the DB but some are long and i want to format them such that when i copy them out of SQL and past them into notepad they have line breaks to break up the otherwise single line that runs on forever and hard to read.
