TF255507: The security identifier (SID) for the following SQL Server login conflicts with a specified domain or workgroup account
When I was configuring the TFS 2010 after completing the installation, I have got the following error message!
This is the brief error message and you can see the details results and solution here
"TF255507: The security identifier (SID) for the following SQL Server login conflicts with a specified domain or workgroup account"
Basically the workgroup account I have choosen to host the TFS databases ( SP2010\STEPBISTEPSQL) is SP2010\Administrator but the original SQL server login account is WIN-5DWGQLQJNRV\Administrator so both conflicting!
To solve this issue, we need to rename the conflicts login and we will see the steps below!
Solution 1: Open the command prompt and type the following command and then hit Enter key!
“sqlcmd -E -S “””
Actually this command is altering the login id with the correct account.
Solution 2: Add the account using the SQL server UI! Open the SQL server and select the Security–>Logins, you could see the conflict login id, just remove this id.
Right click on the logins and then select the New Login..
You will get the following window, enter the Login name and hit OK
That’s all, we are good to go! Here is the renamed login screen!
The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request.
I have got the following error when I was developing a gridview editing on a webpage last week. This is most common issue, even I have faced several times earlier. But I want to keep this solution for beginners!
Here is the full error message:
"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"
My 1st suggestion is just check the cache! Meaning..clear your browser cache and refresh it and see whether it is working? if not continue with one of the following solutions!
1. Enable ViewState is false
Find the control which is giving problem in the page and then disable the ViewState! For me it was a DropDownList so,
<EditItemTemplate> <asp:DropDownList ID="DropDownList1" runat="server" EnableViewState="false"> </asp:DropDownList> </EditItemTemplate>
2. Just place the data binding on the GridView events wherever you use the edit! For and example “RowCancelingEdit”
Protected Sub GridViewRelease_RowCancelingEdit(ByVal sender As Object, ByVal e As GridViewCancelEditEventArgs) Handles GridViewRelease.RowCancelingEdit GridViewReleaseAnalyst.EditIndex = -1 BindData() End Sub
That’s all, No more ViewState issue! Happy Programming!!
