Hello all,

I'm trying to get a sqldatasource value to input into a textbox. How can this be achieved? This column contains terms and conditions, so it contains a large amount of text which is why I need it in the textbox.

<asp:TextBox id="txtTerms" TextMode="multiline" Wrap="true" ReadOnly="true" Height="150px" Width="100%" ForeColor="GrayText" Font-Size="11px" runat="server"></asp:TextBox>

 <asp:SqlDataSource ID="SqlTerms"
                       ConnectionString="<%$ ConnectionStrings:Focus %>"
                       ProviderName="<%$ ConnectionStrings:Focus.ProviderName %>"
                       SelectCommand="SELECT TermsAndConditions FROM tblPPTermsAndConditions                        WHERE ID=1003">

You'd have to handle the Selected event of the SqlDataSource and write the data to the textbox. Otherwise you need to use a control, such as the FormView, that supports direct binding to a data source.

Thanks for the quick response, do you know if there is some code or a link that I can reference to that is an example of this?

Actually scratch that. What you need to do is manually invoke the Select method of the SqlDataSource object, which will return a DataView containing the query results:
System.Data.DataView view = (System.Data.DataView)SqlDataSource1.Select(DataSourceSelectArguments.Empty);
MyTextBox.Text = view[0][1].ToString();

I get "System.Data.DataRowView" as the output in the text box.

This is what I've inserted:
System.Data.DataView view = (System.Data.DataView)SqlTerms.Select(DataSourceSelectArguments.Empty);
txtTerms.Text = view[0].ToString();

You need two sets of square brackets (as in my last post); the first indicates which row you want to take data from (zero if there is only one row), the second is the column.

I get an error on the page:

Cannot find column 1. The line in question is:
Line 24: txtTerms.Text = view[0][1].ToString();

Could it be because I'm only calling for 1 column in the query?

Yes. The snippet was only an example, you will need to change the index values to match your data. So, if you're only pulling back one column, then you will need to specify zero as the column index.
