I am using query strings to pass data from web form to web form and I have two questions. First if i use a asp:sqldatasouce to fill up a grid view and I have my select command set to a paramater that get whatever is in the query string it will not work because whatever is in the quers string gets a " ' " put in front and in the back of it. So if the query string was 5 whene it does the sql statement it sets my paramater = '5' not just 5 so its wont work. How can I fix this using the asp:sql datasource my aspx code looks like
<
asp:SqlDataSourceID="SqlDataSource1"runat="server"ConnectionString="<%$ ConnectionStrings:Rental PropertiesConnectionString %>"SelectCommand="SELECT * FROM [APARTMENTS] WHERE ([PROPERITY_ID] = @.PROPERITY_ID)"><SelectParameters><asp:QueryStringParameterName="PROPERITY_ID"QueryStringField="key"Type="Int32"/></SelectParameters></asp:SqlDataSource>
Also since i have not been able to get around this so i have been wrting code in vb.net to attact a dataset to a grid view to populate it based on the query string i would do the following in vb.net to get ride of the ' in front and behind the query string
Dimy as string ="'" // " ' "
key = Request.QueryString("key").trim(y.tochararray)
But now i am doing another project in C# and I have re-written the above code in C# it will run but it will not take the " ' " out form infront or behind key. How does this need to be changed up?
string
y ="'";
key = Request.QueryString[
"key"].trim(y.tochararray());
If I understand you correctly, you have 5 in database but while you select it, you get '5' correct?
SqlDataSource doesn't put any thing while it gets data. And binding itto Gridview should not be a problem

I am codeing the value of my querystring in depending on a key value in another forms gridview so my code for a query string is
dim key as string 'holds the key value of the selected row in a dataview
response.redirect("Info.aspx?id=' " & key & " ' ")
when i do that, if key is 5 it places a single quote infort and behind five, '5'
So when i have my select statment in my sqldatasource and the paramater is equal to query string id it has the single quote in the select command sent to the database and that produces an erro. How can i take out the " ' " in the query sting in my aspx file ?

Hi draskc03
This is my example. You can try this
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="NewsID" Width ="100%"
DataSourceID="SqlDataSource1" AllowPaging="True" AllowSorting="True" CellPadding="4" ForeColor="#333333" GridLines="None" HorizontalAlign="Center" PageSize="20">
<Columns>
<asp:TemplateField SortExpression="ImageUrl" HeaderText="Edit"><ItemTemplate>
<a href ="AddEditNews.aspx?ID=<%#Eval("NewsID") %>"> <img src ="../images/Edit.gif" border ="0"/></a>
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField ReadOnly="True" DataField="NewsID" InsertVisible="False" Visible="False" SortExpression="NewsID" HeaderText="ID"></asp:BoundField>
<asp:BoundField DataField="AddedDate" SortExpression="AddedDate" HeaderText="AddedDate"></asp:BoundField>
<asp:TemplateField SortExpression="ImageUrl" HeaderText="Title"><ItemTemplate>
<a href ="AddEditNews.aspx?ID=<%#Eval("NewsID") %>"> <%#Eval("Title") %></a>
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="Description" Visible="False" SortExpression="Description" HeaderText="Description"></asp:BoundField>
<asp:BoundField DataField="Body" Visible="False" SortExpression="Body" HeaderText="Body"></asp:BoundField>
<asp:BoundField DataField="ImageUrl" Visible="False" SortExpression="ImageUrl" HeaderText="ImageUrl"></asp:BoundField>
<asp:BoundField DataField="language" SortExpression="language" HeaderText="Language"></asp:BoundField>
<asp:CommandField ShowDeleteButton="True" DeleteText="Xóa" DeleteImageUrl="~/images/Delete.gif" ButtonType="Image" HeaderText="Xoá"></asp:CommandField>
</Columns>
</asp:GridView>
