setting custom list forms to content type

Setting custom display/edit list forms to a content type

What i was aksed to do is if i can create custom form pages that can be set to the items of specific content type. Though i'm not sure of the second part im started with first part,creating the custom form for displayform.aspx.
So, I copied the existing form and added my custom control to it.
I tred to place the new form(customdisplayform.aspx) in the same location(listname\forms\) where OOB forms exist for a library/iist through a feature.
Though feature deploys the form to the location, i see the listformwebpart missing when i open the form in sharepoint designer.
Also, i have to set the propertiesand ListName and ListId of listformwebpart dynamically, so i decided to go for a application page with code behind in which the properties are set onInit as below.

listFormWP.ListName = SPContext.Current.Web.Lists["lib"].ID.ToString();

listFormWP.ListId = SPContext.Current.Web.Lists["lib"].ID;
Now, application page will have the same markup as is just that it will inherit layoutspagebase class.
so now we have the form ready but how to associate with the library or list? here is the code,

SPList list = web.Lists["lib"];
list.DefaultEditFormUrl = "/../_layouts/mlp/CustomEditForm.aspx";

list.DefaultDisplayFormUrl = "/../_layouts/mlp/CustomDisplayForm.aspx";

list.update();

Custom list forms can also be associated to content type as below,

SPContentType reportCT = list.ContentTypes[contentType];


reportCT.DisplayFormUrl = "/../_layouts/mlp/CustomDisplayForm.aspx";

reportCT.EditFormUrl = "/../_layouts/mlp/CustomEditForm.aspx";

reportCT.Update();

Please let me know if anybody found something on the missing markup issue when custom list form is provisioned inside the path of the library rather under layouts.

 

Binding objectdatasource to SPGridView for Sorting

Today I have a simple requirement, to achieve filtering and sorting on a simple grid.

Asp.Net GridView do not have an option to filter by default but where as SPGridView provides as part of the control.

I have simple method, that will form the data into DataTable which will be set as datasource to SPGridView as shown in below code.

<SharePoint:SPGridView runat="server" ID="reportsList" AutoGenerateColumns="false"PageSize="1" AllowPaging="false"

AllowSorting="true"  AllowFiltering="false" FilterDataFields="Col1,Col2,Col3,Col4" >

    <Columns>

        <asp:TemplateField HeaderText="Col1" SortExpression="Col1">

            <ItemTemplate>

                <asp:HyperLink ID="Col1Link" runat="server" Text='<%# Eval("Col1") %>'NavigateUrl= '<%# Eval("Col5") %>'   />

            </ItemTemplate>

        </asp:TemplateField>

            <asp:TemplateField HeaderText="Col2" SortExpression="Col2">

            <ItemTemplate>

                <asp:HyperLink ID="TabLink" runat="server" Text='<%# Eval("Col2") %>'NavigateUrl= '<%# Eval("Col6") %>'  />

            </ItemTemplate>

        </asp:TemplateField>

                                   

        <SharePoint:SPBoundField HeaderText="Col3" SortExpression="Col3" DataField="Col3" />

        <SharePoint:SPBoundField HeaderText="Col4" SortExpression="Col4" DataField="Col4" />

    </Columns>

    <EmptyDataTemplate>   No data.</EmptyDataTemplate>

</SharePoint:SPGridView>

above markup is also an example for binding hyperlink fields in spgridview.

protected override void CreateChildControls()

        {

            base.CreateChildControls();

            using (SPSite site = new SPSite(SPContext.Current.Site.Url))

            {

                using (SPWeb web = site.OpenWeb())

                {

                  

                    // bind the datasource to grid

                    reportsList.DataSource = GetMyDataTable();

                    reportsList.DataBind();

                  

                }

            }

           

        }

So easy and simple to see the grid populated with data on the page, but when I choose to sort a column I get the below error .

The GridView 'GridViewID' fired event Sorting which wasn't handled

Googling around I found that property, DataSourceID need to set instead of setting DataSource. Not sure why.

So now I have to rewrite the code and bind some type of datasource(objectdatasource/SPdatasources/…/).

As we know, ObjectDataSource is simple and easy I started with it and then lately realized that I have to create objects, I mean new type that will be used by ObjectDataSource as suggested by all other blogs.

But I do not want to write extra code but directly bind the existing datatable as objectdatasource for which blogs suggest to create type and write a method that will convert it to datatable which seem to be round way for me.

So I tried the below code and able to achieve sorting without a new Type/object definition. Still i could not get filtering work..at least it did not throw any error in log or on page.

//populate the datasource

                    ObjectDataSource  reportsDataSource = new ObjectDataSource();

                    reportsDataSource.ID = "reportsDataSource";

                    reportsDataSource.SelectMethod = "GetMyDataTable";

                    reportsDataSource.TypeName = this.GetType().AssemblyQualifiedName;

                    this.Controls.Add(reportsDataSource);

                    

                    // bind the datasource to grid

                    reportsList.DataSourceID = "MyDataSource";//  = 

                    reportsList.DataBind();

 

Read SharePoint Service using JQuery

I had spent a day to know that soap response can be read at the event complete but not success.
In success event soapresponse(data.responseXML) is always empty. I'm not sure if its a sepcial case with soap.

Below function of Jquery retrieves the SocialTag count of a specific URL from all users.
Complete event triggers all the time after the service call resulting in success or error. So i used a flag based on which i can get to know if the service call is success or error.

function GetLikeCountFromService(domId, url) {

var tagName = "I like it";

var queryStatus = true;

var soapEnv =

"<soap:Envelope xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xmlns:xsd='http://www.w3.org/2001/XMLSchema' xmlns:soap='http://schemas.xmlsoap.org/soap/envelope/'>\

<soap:Body> \

<GetTagTermsOnUrl xmlns='http://microsoft.com/webservices/SharePointPortalServer/SocialDataService'>\

<url>" + url + "</url>\

<maximumItemsToReturn>'100</maximumItemsToReturn> \

</GetTagTermsOnUrl> \

</soap:Body> \

</soap:Envelope>";

$.ajax({

url: '/_vti_bin/socialdataservice.asmx',

type: 'POST',

dataType: "xml",

data: soapEnv,

complete: function (data) {

//process only if the query is success

if (queryStatus) {

var likeCount = 0;

$(data.responseXML).find("SocialTermDetail").each(function () {

var term = $(this).find("Term").find("Name").text();

//alert($(this).find("Term").find("Name").text());

if (term == tagName) {

likeCount = $(this).find("Count").text();

// set the like count

$(domId).text(likeCount);

return;

}

});

,

error: function (all, textStatus, errorThrown) { queryStatus = false; alert(errorThrown); },

contentType: "text/xml; charset=\"utf-8\""

});

}

JQuery made life easy with flexible API. I have implemented another function similar to it that will like a URL, in sharepoint terms tagging a url with "I Like It". As a combination this will work as similar to the Social Like feature in Facebook.
