SharePoint development, sharepoint

This article describes some novel SharePoint instance applications, which have been used in projects for Party A. The data is too large and the customer has Excel, which requires batch import.

Roughly as follows:

This instance is imported by using the data view of the list. The data view is similar to Excel, so you can directly edit it, or even paste it directly from Excel, click Save to insert the data to the list.

First, we need a list. The list field corresponds to Excel. In my instance, select create list definition and list instance (how to create a project is not a waste of effort)

Create method stamp here

After the list instance is completed, add an event Receiver acting on the list to process Background operations. Add an event receiver, select Delete, added, and updated events to complete the creation.

You can write the core code. In our actual application, a temporary table is created to process the data here. Click Save on the page and then go to the real data table.

Next, we want to be more automated. We will automatically create a data view for this list and set it to the default view for specialized import operations.

Process the FeatureActivated event. The core code in the instance is as follows:

SPWeb _ web = properties. feature. parent as SPWeb; SPList list = _ web. lists. tryGetList ("basic owner list import"); SPList listTwo = _ web. lists. tryGetList ("internal list basic import"); SPView newView = null; SPView newViewTwo = null; string strQuery = default (string); string strQueryTwo = default (string ); stringCollection strCol = new StringCollection (); StringCollection strColTwo = new StringCollection (); newView = list. views. cast <SPView> (). firstOrDefault (v => v. title = "Owner list basics"); if (newView = null) {strCol. clear (); strCol. add ("Title"); strCol. add ("Ye_zhqdmch"); strCol. add ("Qing_dxmtzh"); strCol. add ("Dan_w"); strCol. add ("Qing_dl"); strCol. add ("Qian_zhl"); strCol. add ("Yan_shl"); strCol. add ("He_tdj"); strCol. add ("Ye_zhqrdj"); strCol. add ("Yu_jjsdj"); strCol. add ("Yu_jshjbl"); strCol. add ("Jue_sdj"); newView = list. views. add ("Default", strCol, strQuery, 30, true/** // * Whether paging is supported */, true/** // * whether it is the Default view */, Microsoft. sharePoint. SPViewCollection. SPViewType. grid, false); newView. title = "Owner list basics"; newView. update ();} newViewTwo = listTwo. views. cast <SPView> (). firstOrDefault (v => v. title = "internal configuration basics"); if (newViewTwo = null) {strColTwo. clear (); strColTwo. add ("Title"); strColTwo. add ("Nei_bqdbm"); strColTwo. add ("Nei_bqdmch"); strColTwo. add ("Xiang_mtzh"); strColTwo. add ("Dan_w"); strColTwo. add ("Gong_chshl"); strColTwo. add ("Ding_e"); strColTwo. add ("Ren_gf"); strColTwo. add ("Ji_xf"); strColTwo. add ("Qu_ybm"); strColTwo. add ("Qu_ymch"); newViewTwo = listTwo. views. add ("Default", strColTwo, strQueryTwo, 30, true/** // * Whether paging is supported */, true/** // * whether it is the Default view */, Microsoft. sharePoint. SPViewCollection. SPViewType. grid, false); newViewTwo. title = "internal configuration basics"; newViewTwo. update ();}

The last step is to apply it on the application page (here I only describe the instance situation, and you can choose the specific application) and add an iframe element on the page, you can introduce the URL of the List View.
