I think you need to set the environment variable for that.

You have to use MySql.Data.dll
Place it in C:/windows/System32 and refer it in your application.

Hi All,
I have Datatable, which is created at runtime and Bind with GridView.What I want is to make two columns of that datatable visible false.
Please tell me how do I go about the same.
Thanks in advance...

|
|
I think you want to make columns of the gridview to be invisible not os the datatable, right?

Actually you are right but I tried that on RowDataBound event but it didnt work.
Any help??
|
|
|
|
|
I think when you are binding the gridview at that time you can make them visible = false (Can't you do that in design time). Are you creating the gridview dynamically?

Actually I am binding Gridview with ViewState DataTable on Add button click.Following is the code:
strSql = "SELECT ColumnName, ColumnDataType FROM sysDataTypeTable WHERE ID =" & cmbGFormName.Items(cmbGFormName.SelectedIndex).Value
objDT = objDB.ExecuteDatatable(strSql)
If Not ViewState("WhereClause") Is Nothing Then
'DataTable is available in ViewState
GridViewQuery.AutoGenerateColumns = True
If htxtEditOrAdd.Value = "Edit" Then
index = htxtSrNo.Value
If cmbGFormName.SelectedIndex <> 0 And cmbOperator.SelectedIndex <> 0 Then
CType(ViewState("WhereClause"), Data.DataTable).Rows(index).Item("FieldName") = cmbGFormName.Items(cmbGFormName.SelectedIndex).Text
CType(ViewState("WhereClause"), Data.DataTable).Rows(index).Item("Operator") = cmbOperator.Items(cmbOperator.SelectedIndex).Text
CType(ViewState("WhereClause"), Data.DataTable).Rows(index).Item("Value") = txtValue.Value
If chkAndOR.Checked Then
CType(ViewState("WhereClause"), Data.DataTable).Rows(index).Item("ANDOR") = "OR"
Else
CType(ViewState("WhereClause"), Data.DataTable).Rows(index).Item("ANDOR") = "AND"
End If
GridViewQuery.DataSource = ViewState("WhereClause")
GridViewQuery.DataBind()
htxtEditOrAdd.Value = ""
htxtSrNo.Value = ""
End If
Else
If cmbGFormName.SelectedIndex <> 0 And cmbOperator.SelectedIndex <> 0 Then
Dim objDR As DataRow
objVDT = ViewState("WhereClause")
objDR = objVDT.NewRow()
objDR("FieldName") = cmbGFormName.Items(cmbGFormName.SelectedIndex).Text
objDR("Operator") = cmbOperator.Items(cmbOperator.SelectedIndex).Text
objDR("Value") = txtValue.Value
If chkAndOR.Checked Then
objDR("ANDOR") = "OR"
Else
objDR("ANDOR") = "AND"
End If
objDR("ColumnDataType") = objDT.Rows(0).Item(1).ToString
objDR("ColumnName") = objDT.Rows(0).Item(0).ToString
objVDT = ViewState("WhereClause")
objVDT.Rows.Add(objDR)
GridViewQuery.DataSource = ViewState("WhereClause")
GridViewQuery.DataBind()
End If
End If
Else
objVDT = New DataTable("WhereClause")
objDC = New DataColumn
'Sr No Column
objDC = objVDT.Columns.Add("SrNo", System.Type.GetType("System.String"))
objDC.Caption = "Sr No"
objDC.AutoIncrement() = True
'Field Name Column
objDC = objVDT.Columns.Add("FieldName", System.Type.GetType("System.String"))

objVDT.Columns.Add(New DataColumn("ColumnName"))
ViewState("WhereClause") = objVDT
Dim objDR As DataRow
objDR = objVDT.NewRow()
If txtValue.Value <> "" Then
objDR("SrNo") = 1
objDR("FieldName") = cmbGFormName.Items(cmbGFormName.SelectedIndex).Text
objDR("Operator") = cmbOperator.Items(cmbOperator.SelectedIndex).Text
objDR("Value") = txtValue.Value
If chkAndOR.Checked Then
objDR("ANDOR") = "OR"
Else

End If
<b>'Make this 2 columns visible false.</b>
objDR("ColumnDataType") = objDT.Rows(0).Item(1).ToString
objDR("ColumnName") = objDT.Rows(0).Item(0).ToString
objVDT.Rows.Add(objDR)
GridViewQuery.DataSource = objVDT
GridViewQuery.DataBind()
End If
End If
Please tell me how do I make it visible false??

You use to scare with these looong sode snippets.. 
I think just after you bind the gridview you can simply hide the column by using
GridView1.Columns[1].Visible = false;
or also just when you binding the gridview one event gets fired just as onitemdatabound in datagrid there also it can be done...

I have tried this but its not working.
GridViewQuery.Rows(SrNo).Cells(2).Text = objDT.Rows(0).Item(1).ToString
GridViewQuery.Columns(2).Visible = False
GridViewQuery.Rows(SrNo).Cells(3).Text = objDT.Rows(0).Item(0).ToString
GridViewQuery.Columns(3).Visible = False
Its giving runtime error that index was out of range.

|

You first check whether that many columns are there or not. If you are having the columns then certainly you can make them visible false with that code.

What I am doing is taking 2 Bound Columns in gridview(which I have to hide)and then binding it viewstate datatable with gridview. but it gives runtime error.
|
|
|
|
|
You check the columns count and then try to hide. Check whether you are having that columns or not after you bind.

I got some code on google but it showing some error:
Dim mt As DataTable
' Define datatable
Dim col As DataColumn
' Define columns
newGrid.DataSource = mt
' define datasource for datagrid
For Each col In mt.Columns
' go through all the columns
Dim dg As New BoundColumn()
' create a new bound column
dg.DataField = col.ColumnName
' define the column name in datagrid
newGrid.Columns.Add(dg)
' add the column to datagrid
If col.ColumnName = "ID" Then
' if the field is a unique id
newGrid.Columns(col.Ordinal).Visible = False '
set visible = false
End If
Next
newGrid.DataBind()
it giving error on newGrid.Columns.Add(dg) line.It says cannot control to System.Web.UI.WebControls.BoundColumn to System.Web.UI.WebControls.DataControlField.
Trying to analysis the code.
If u can help me for the same.

I think you can assign commandname property of the button and then can identify on the basis command them in the event.

Hello & smiles,
Can someone kindly guide as to what is going wrong in my Sub below? I am getting the error as :
System.Data.SqlClient.SqlException: The INSERT statement conflicted with the FOREIGN KEY constraint "FK_ProfitLossData_CBValues". The conflict occurred in database "ProfitLossRegister", table "dbo.CBValues", column 'cbno'. The statement has been terminated.

Commandsave.Connection = connectionsave
Try
connectionsave.open()
'iterate through all the gridrows

'cbno' is a foreign key on my table. The values of cbno are displayed on the gridview with a Join when the grid loads. I have to save these values in my master table so I am reading the the value of cbno for each row in a label(with findcontrol) and then inserting this label value into the mastertable but in the cbno column which is a foreign key.
I hope I haven't confused you all. Please help!
Thank you.
Aartee.
