Question

This might be very basic question to some but I am struggling for quite some time.

I created an aspx page which has a search ability on User Table (Database). When Search button is cliked related Grid is filled with UserNames. And I put an Edit HyperLink in every row right next to UserName Column.

However Edit button should get a parameter named “UserCode” (this information also comes when I retrieved the names) but I just couldn’t write the appropriate code to the related line. Please in my codes there is a line contains I DONT KNOW WHAT TO TYPE IN HERE. Instead of index solution, any other suggestions are welcome.

    DataTable oDataTable;
    DataView oDataView;

    protected void SearchLinkButton_Click(object sender, EventArgs e)
    {
        MembershipUserCollection allUsers = Membership.GetAllUsers();
        if (allUsers != null)
        {
            oDataTable = new SystemUserAccountBsWrapper().SearchAllUsers(null); //Fetchs all user data
            oDataView = oDataTable.DefaultView;
            oDataView.Sort = "UserName";
            oDataView.RowFilter = "UserName LIKE '%" + UserNameTextBox.Text + "%'";
            UserGridView.DataSource = oDataView;
            UserGridView.DataBind();
        }
    }
    protected void UserGridView_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            HyperLink EditHyperLink = (HyperLink)e.Row.FindControl("EditHyperLink");
            EditHyperLink.NavigateUrl("EditUserInfo.aspx?key=" + oDataTable.Rows[**I DONT KNOW WHAT TO TYPE IN HERE**]["UserCode"]);
        }
    }

Sorry for my bad English.

Answer 1

DataBinder.Eval can be used on codebehind also

EditHyperLink
      .NavigateUrl("EditUserInfo.aspx?key=" + DataBinder.Eval(e.Row.DataItem,"UserCode"),650, 500, true);
