Sharepoint Proxy Web Part - Configure The Web Part To Point To An Existing Web App

Feb 17, 2010

We have several asp.net web applications we've built and we also want to embed them into various sharepoint pages. We need to have them look like standalone applications when viewed in their own pages, but also have them look like they fit within the sharepoint page when embedded. We are doing this currently with IFrames and it works ok, but I'm wondering if there is some sort of proxy web part where we can configure the web part to point to an existing web app and it will proxy the contents through from the web app into the sharepoint page removing the need for an IFrame. Possible?

C# - SharePoint Web Part Gallery Details Of Each Web Part

Mar 2, 2011

When using SPWeb.GetCatalog(SPListTemplateType.WebPartCatalog), it returns an SPList which of course contains a SPListItemCollection of the web parts in the web part gallery. When looping through the items, is there any easy way to get properties of the web parts? Such as AllowClose, CatalogIconImageUrl, etc... I know I can probably accomplish this using the listItem.OpenBinaryStream etc and loading the xml of the .webpart file, but I wondered if there was an easier way to do this.

Forms Data Controls :: Delete Confirmation Box In Gridview With Edit And Delete Buttons?

Nov 18, 2010

How do I reference the delete button to add the delete confirmation box when I have both the Edit and Delete buttons as the last two columns in the Gridview control. The following code works fine without any issues when I have the delete button only:

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType != DataControlRowType.DataRow) return;
int lastCellIndex = e.Row.Cells.Count - 1;
Button db = (Button)e.Row.Cells[lastCellIndex].Controls[0];
db.OnClientClick = "if (!window.confirm('Are you sure you want to delete this record?')) return false;";
}

But, when I have both the Edit and the Delete buttons, I get the following error when I click the edit button while the delete button works fine.

Specified argument was out of the range of valid values. Parameter name: index

How do I reference the delete button so the edit button is not affected in this case?

Forms Data Controls :: Delete Images From Folder Using Gridview Delete Link?

Feb 3, 2010

Using "Enable Delete" from Gridview control, I can delete (besides, update, sort, paging, etc) data from the database (this is done automatically). However, how can I delete the actual image that resides in my image folder (i.e. from "pix" folder )? What is the best way to delete image? If using code behind, how? Please write a full code for me. Here is my source code.

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="photoID"

Forms Data Controls :: Have A Grid Contol That Allows Delete What Would Like To Have Is Someway To Say Are You Sure You Want To Delete?

Feb 8, 2010

I have a grid contol that allows delete what I would like to have is someway to say Are you sure you want to delete?I found this code online, and tried it but it did not work, Do I need something more some behind code maybe?Here is what I found online:Adding 'Delete Protection' to controls If you use a control set up to allow Delete, the Delete button gives a straight delete without any warning, which can be dangerous.To give a warning dialog box, add an OnClientClick event to the Delete button, as follows.

<asp:LinkButton
ID="DeleteButton"
runat="server" CausesValidation="False"
CommandName="Delete"
OnClientClick="return confirm('Are you sure you want to delete this record?');"
Text="Delete">
</asp:LinkButton>

Here is my code: You can see where I added the code from above.

<ItemTemplate>
ID:<asp:label id="IDLabel" runat="server" Text='<%# Eval("ID") %>' /><br />
Name:<asp:label id="NameLabel" runat="server" Text='<%# Bind("Name") %>' /><br />
Destination:<asp:label id="DestinationLabel" runat="server" Text='<%# Bind("Destination") %>' /><br />
OutDate:<asp:label id="OutDateLabel" runat="server" Text='<%# Bind("OutDate") %>' /><br />
ReturnDate:<asp:label id="ReturnDateLabel" runat="server" Text='<%# Bind("ReturnDate") %>' /><br />
LeaveTime:<asp:label id="LeaveTimeLabel" runat="server" Text='<%# Bind("LeaveTime") %>' /><br />
ReturnTime:<asp:label id="ReturnTimeLabel" runat="server" Text='<%# Bind("ReturnTime") %>' /><br />
ContactNumber:<asp:label id="ContactNumberLabel" runat="server" Text='<%# Bind("ContactNumber") %>' />
<asp:linkbutton id="EditButton" runat="server" CausesValidation="False" CommandName="Edit" Text="Edit" />
<asp:linkbutton id="DeleteButton" runat="server" CausesValidation="False" CommandName="Delete" OnClientClick="return confirm('Are you sure you want to delete this record?');" Text="Delete" />
<asp:linkbutton id="NewButton" runat="server" CausesValidation="False" CommandName="New" Text="New" />
</ItemTemplate>

Forms Data Controls :: How To Insert Delete Confirmation Dialog To Gridview Delete Button

Apr 6, 2010

I am using Sharepoint Designer and trying to insert a Delete button into a gridview. I added this to the top of my ASPX:

<%@ Register Tagprefix="SharePoint" Namespace="Microsoft.SharePoint.WebControls"
Assembly="Microsoft.SharePoint, Version=11.0.0.0, Culture=neutral,
PublicKeyToken=71e9bce111e9429c" %>

and I added this as a Gridview column:

<SharePoint:DeleteItemButton
runat="server"
ID="CustomFormDeleteItemButton"
ControlMode="Edit"
/>

and this is the error I get:

An error occurred during the processing of . System.Web.UI.WebControls.DataControlFieldCollection must have items of type 'System.Web.UI.WebControls.DataControlField'. 'SharePoint:DeleteItemButton' is of type 'Microsoft.SharePoint.WebControls.DeleteItemButton'.

Data Controls :: Delete With Confirmation Using Details View Delete Command Button

Nov 7, 2011

I am interested in building an intranet document management system to be used from Internet Explorer using ASP.net, VB.net, and MS SQL Server but have no experience in doing a project like this. Supported file types would be txt, pdf (from scanner or imported from file system), or jpg. What concepts I should look at researching/learning about to build the system in a way that files will be stored as small as possible, retrieved and displayed quickly, and secured. The users would be spread out over a regional area covering 4 states.

Forms Data Controls :: Dynamic Delete LinkButton In ListView Error "Delete Can Only Be Called On A Valid Data Item"

Feb 22, 2010

I need you assistance, Dynamic Delete LinkButton with CommandName=Delete gives me an error: Delete can only be called on a valid data item. nfact I am designing a Complex Grid using .Net 3.5 ListView Control with Scrollbar and Fixed Toolbar: This grid consist of 3 Tables:

1- footer
2- Toolbar Control

ImageButton with funnel icon is with CommandName="Filter"
ImageButton with magnifier icon is with CommandName="View"
ImageButton with stop icon is with CommandName="Delete"

Web Forms :: Getting The ID Of A Web Part?

May 28, 2010

When web parts are loaded into a page, the source code shows, for example, the following format to identify a particular web part.

id="ctl00_Header_WebPartManager1_wp1058756736"

This unique ID remains the same for a Web Part once it has been loaded into the page.

I have a custom class which constructs certain web parts each time they are loaded into a page. I need to access this web part id to make changes to the web part before it is loaded.

In my custom class I can access the WebPartManager.ClientID, which gives me:

ctl00_Header_WebPartManager1

How do I access the unique Web Part ID?

(any code snippets in VB, please).
