What did you do for the Random ID..? I am having same problem and I am not able to fix it. Please help me.

Here is My code.

 Using DB As New LocalDB
            For Each Panel In (From c In DB.CollapsePanelTypes Where c.CreatorID = UserID).ToList
                Dim IsExists As Boolean = False
                For Each Web As WebPart In WebPartManager.WebParts
                    Response.Write(Web.ID & "<br>")
                    'If Web.ID.StartsWith("wp") Then
                    '    IsExists = True
                    'End If
                Next
            
                If Not IsExists Then
                    
                    Dim Control = LoadControl("~/Controls/PersonalisedPanel.ascx")
                    With CType(Control, PersonalisedPanel)
                        .ID = "PersonalisedPanel" & ID
                        .VisitorName = VisitorName
                        .PanelID = Panel.ID
                        .IsReadOnly = IsReadOnly
                        .VisitorName = VisitorName
                        .IsOwnProfile = IsOwnProfile
                        .IsAdmin = IsAdmin
                    
                        Dim ZoneIndex = Zone1.WebParts.Count

                        Dim gwp As GenericWebPart = WebPartManager.CreateWebPart(Control)
                        gwp.ChromeType = PartChromeType.None
                        gwp.ID = "manish"
                        gwp.Title = "Manish"
                        If ZoneIndex = 0 Then
                            WebPartManager.AddWebPart(gwp, Zone1, ZoneIndex)
                        Else
                            WebPartManager.AddWebPart(gwp, Zone1, ZoneIndex + 1)
                        End If
                        WebPartManager.SetDirty()
                    End With
                End If
                    
            Next
        End Using

Please tell me where I am wrong.

Thanks.

hello ramireddy,

Above code is working perfactly.. the only change I had to do is changing the condition of checking the ID of dynamically

generated webpart as it generated some random no behind the variavle name wp.. dont know why it is doing so..

but the final code looks like below..

Boolean WebPartExists = false;
                foreach (WebPart wp in WebPartManager1.WebParts)
                {
                    if (wp.ID.StartsWith("wp"))
                        WebPartExists = true;
                }
                if (!WebPartExists)
                {
                    Control uc = this.LoadControl("control1.ascx");
                    uc.ID = "wp2";
                    GenericWebPart wp2 = WebPartManager1.CreateWebPart(uc);
                    wp2.AllowZoneChange = true;
                    wp2.Title = "dynamic webpart";
                    WebPartManager1.AddWebPart(wp2, WebPartZone1, 0);
                    WebPartManager1.SetDirty();
                }

Thanks man....

you can check like below.

Boolean WebPartExists = false;
            foreach (WebPart wp in CustomWebPartManagerControl1.WebParts)
            {
                if (wp.ID == "wp2")
                    WebPartExists = true;
            }
            if (!WebPartExists)
            {
               // your webpart add code
            }

Hello ramireddy,

I am sending you the code snippet,

protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                HttpCookie authCookie = Request.Cookies.Get(FormsAuthentication.FormsCookieName);
                if (authCookie == null)
                {
                    string MyCookieName = "Reminder";
                    System.Web.HttpCookie MyCookie = Request.Cookies.Get(MyCookieName);
                    string UserID = null;

Hello ramireddy,

Thanks for your detail description.. I added Assembly attribute in Register tag and the problem was solved.

but now I stuck with another problem which I cant figure out.

Problem is when I executed the application first time it shows all fine but when I close the explorer and run it in another explorer

the webpart is getting duplicated. I can see two webpart with name webpart [1] and webpart [2].

each time it is generating new one wich name webpart [N].. can you tell me pls what wrong..

Re: Drag drop dynamically generated webpart

ramireddyindia — Mon, 29 Jun 2009 05:54:42 GMT

step1: this is the custom webpart manager i created.

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Text;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
namespace CustomWebPartManager
{
    [DefaultProperty("Text")]
    [ToolboxData("<{0}:CustomWebPartManagerControl runat=server></{0}:CustomWebPartManagerControl>")]
    public class CustomWebPartManagerControl : WebPartManager
    {
        [Bindable(true)]
        [Category("Appearance")]
        [DefaultValue("")]
        [Localizable(true)]
        public string Text
        {
            get
            {
                String s = (String)ViewState["Text"];
                return ((s == null) ? String.Empty : s);
            }

            set
            {
                ViewState["Text"] = value;
            }
        }
        public void SetDirty()
        {
            // Invoke the protected SetPersonalizationDirty method      
            SetPersonalizationDirty();
        }
    }
}

step2: Build this custom control Application, it will build successfully.

step3: Now go to your original application. there go to your toolbox, add a tab and right click there, choose the options, choose items. now a dialog box will come, through browse button, choose the dll file, that built in the custom control, now click ok.

then a control will add to your toolbox.

step4: Now drag that control into your webpage, in the place of webpartmanager. (when you drag, automatically the reister tag will come)

step5: Now Call the setDirty() method immediately after you adding your webpart.

Drag drop dynamically generated webpart

joshijimit — Fri, 26 Jun 2009 11:23:11 GMT

hello All,

I am new in webpart.

I am adding a usercontrol dynamically to a webpartzone.

It is displaying properly but when I am trying to drag it, It will disapear.

I am herewith sending you code snippet.

if (!IsPostBack)
{

Control uc = this.LoadControl("control1.ascx");
                uc.ID = "wp2";
                GenericWebPart wp2 = WebPartManager1.CreateWebPart(uc);
                wp2.AllowZoneChange = true;
                wp2.Title = "dynemic webpart";
                WebPartManager1.AddWebPart(wp2, WebPartZone1, 1);
            }

Can you tell me can I drag this control from one zone to another?

thanks in advance
