Question

I have a repeater that lists data including an ID that I pass to a user control that is not visible until I click a linkbutton. However, when I have clicked the linkbutton, the ID has been lost.

Anyone have any idea where I’m going wrong?

Here is the code for the repeater:

<asp:Repeater ID="uxPolicyList" runat="server" onitemdatabound="uxPolicyList_ItemDataBound">
        <ItemTemplate>
                    <tr>
                        <td class="smaller-ctrl">
                            <img src="Assets/Images/home-icon.gif" alt="Home Insurance Policy" /><%#Eval("PolicyNumber")%>
                        </td>
                        <td>
                            <%#Eval("StartDate","{0:d}")%>
                        </td>
                        <td class="center-cell-ctrl">
                            <%#Eval("Renewal", "{0:d}")%>
                        </td>
                        <td class="center-cell-ctrl">
                            Postcode:<br />
                            <%#Eval("Postcode")%>
                        </td>
                        <td id='<%#Eval("PolicyNumber")%>' class="button-cell">
                            <asp:LinkButton ID="uxPolicySummaryButton" CssClass="policy-link-ctrl" CommandName="PolicyNumber" CommandArgument='<%#Eval("PolicyNumber")%>' OnCommand="uxPolicySummaryButton_Command" runat="server">Policy summary<br /></asp:LinkButton>

                        </td>
                    </tr>
                    <uc1:PolicySummary ID="uxPolicySummary" PolicyNumber='<%#Eval("PolicyNumber")%>' runat="server" Visible="false" />
        </ItemTemplate>

I have these get/set accessors in the user control code-behind, but they’re always blank:

public string _policyNumber = string.Empty;

    public string PolicyNumber
    {
        get
        {
            return _policyNumber;
        }
        set
        {
            _policyNumber = value;
        }
    }

When testing, I hard coded a value in the user control. i.e.

<uc1:PolicySummary ID="uxPolicySummary" PolicyNumber="545545-5454-54545" runat="server" Visible="false" />

…and it worked fine. Any ideas appreciated

Answer 1

try to reassign value of PolicyNumber property inside OnCommand event with the value of CommandArgument

Edit

or save it into HiddenField inside your control

public string PolicyNumber
{
    get
    {
        return MyHiddenField.Value;
    }
    set
    {
        MyHiddenField.Value = value;
    }
}
