I had created a web part in Visual Studio 2010 for Sharepoint 2010. I added all the fields, implemented cascading dropdowns, custom panel and bind the data using Sharepoint SPLists

            var collection = mysite.Lists;

            SPListItemCollection valList = mysite.Lists["MyValidationList"].Items;

            ddlCompanyName.DataSource = valList.GetDataTable();

            ddlCompanyName.DataTextField = "Title";


The problem is how to handle the submit buttons.

Like after i click the submit button i want to redirect to the lists page.

Similarly how can i create the edit form like how do i know which record is being modified

Can i use querystring..

Any help is appreciated.

Please note i am not using any third party library

to get the url its:

string url = SPContext.Current.Site.Url + "/" + mysite.Lists["MyValidationList"].RootFolder.Url;

add the above to the button url,

as an example im creating a button and adding the url to the button click event:

METHOD 1 within create child controls

string url = SPContext.Current.Site.Url + "/" + mysite.Lists["MyValidationList"].RootFolder.Url;

Button b = new Button();
b.PostBackUrl = url;

this method is assigning the url on the creation of the button.


create a global varible to hold the url:

string url = null;

create your button within creatchildcontrols event:

        Button b = new Button();
        b.Click += new EventHandler(b_Click);
        url = SPContext.Current.Site.Url + "/" + mysite.Lists["MyValidationList"].RootFolder.Url;

now we have created a button and a click event you want to populate the url you can do like so:

    private void b_Click(object sender, EventArgs e)
        Button b = sender as Button;
        b.PostBackUrl = url;

this method is assigning the url on the click event of the button.

  • Thats great but can you please tell me the other part of the question that how to replace the existing/default forms for edit and create with my new webparts and how to get the record being edited. I cannot find any documentation for them

  • when you say edit form, you mean you want to change the default edit form when editing a list item and you want to replace it with your webpart?

  • Yes thats correct but all the sample i find out show steps to create a application page etc etc but then dont show how can i use my custom buttons etc. My Webpart is doing all the work itself and is not required any other facility. What i am unsure is that what will happen to the Save etc button that are in ribbon and how can i update the item being edited. I am using Sharepoint 2013

  • Similarly while saving the record i am using SPListItem item = null;//valList[(Guid)]; But i am not able to find the Guid. How can i get this? While filling the form i am using .GetDataTable() and then using Select command
