Dynamic LinkButton persistance

[Mordaque]

Hi,

I create dynamic Link Button in my grid depending on DateFields.

I have had a TemplateColumn like this

<telerik:GridTemplateColumn HeaderText="Action" UniqueName="tplColAction">
                    <ItemTemplate>
                        <asp:Panel ID="pnlActionStatut" runat="server" HorizontalAlign="left">
                        </asp:Panel>
                    </ItemTemplate>
</telerik:GridTemplateColumn>

In my code behind i do that

protected void rdGridOpportunite_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if (e.Item.ItemType != GridItemType.Item && e.Item.ItemType != GridItemType.AlternatingItem) return;

        //Get Object Entity
        OpportuniteEntity opp = e.Item.DataItem as OpportuniteEntity;
        if (opp == null) return;

        //Get Panel
        Control pnl = e.Item.FindControl("pnlActionStatut");
        if (!(pnl is Panel)) return;

        //Get All statut associate of this statut
        List<TypeStatutOpportuniteEntity> statuts = TypeManager.GetStatutAssocieOfStatut(opp.TypeStatut.IDType, Profile.InstanceID).ToList();
        if (statuts.Count == 0) return;

        LinkButton lbAction;

        //Create LinkButton for each Statut
        statuts.ForEach(s =>
            {
                lbAction = new LinkButton();
                lbAction.Text = "--> " + s.Libelle;
                lbAction.Click += new EventHandler(lbAction_Click);
                lbAction.CommandArgument = string.Format("{0};{1}", opp.ID, s.IDType);
                lbAction.ID = string.Format("lnkBtn{0}{1}", opp.ID, s.IDType);
                pnl.Controls.Add(lbAction);
                pnl.Controls.Add(new Label() { Text = "<br />" });
            }
        );
    }

My Grid can be expan or collapse and when I Expand or collapse i Lost my control ...
Ditto When I click on LinkButton i lost control too and i can't start GridCommand and lbAction Event click

I have try to make the same code on ItemCreated but the result is the same.

How I can keep my control ??

Thank you.

Thank for your answer.

I have always a problem when I expand my row my dynamic links disapear...

I have tried to Rebind the Grid but when i do that i lost the expand command so my Row is never expand ...

I havn't find the solution in your link.

Regards.

Hello Mordaque,

I would suggest you to handle the RadGrid_ItemCreated event in order to achieve the required functionality. Please refer to the following forum post which elaborates on similar scenario.
