value does not fall withing expected range

Question

I have created timer job and in Execute method of job i have below code which create list

 using (SPSite oSPsite = new SPSite("http://myurl"))
            {
                oSPsite.AllowUnsafeUpdates = true;

                using (SPWeb oSPWeb = oSPsite.OpenWeb())
                {
                    oSPWeb.AllowUnsafeUpdates = true;

                    /* 1. create list from custom ListTemplate present within ListTemplateGalery */
                    SPListTemplateCollection lstTemp = oSPsite.GetCustomListTemplates(oSPWeb);
                    SPListTemplate template = lstTemp["MyTaskList"];
                    oSPWeb.Lists.Add("List Name", "Description", template);


                    /* 2. create list from sharepoint list content type (e.g. Links) */
                    oSPWeb.Lists.Add("List Name", "Description", SPListTemplateType.Links);

                    oSPWeb.AllowUnsafeUpdates = false;
                }

                oSPsite.AllowUnsafeUpdates = false;
            }

When i debug i get error on this line

SPListTemplate template = lstTemp["MyTaskList"];

The error is value does not fall within expected range

What could be reason of error? I have also tried to increase value of List View Lookup Threshold to 800 which is under central administration. But nothing is working.

Answer 1

You can upload the MyTaskList in your list templates gallery at the root web and then try to run your code again.Before testing it in a timer job , you can create a console application and test the same.

Answer 2

To get the custom list template collection, we have to use the RootWeb property of the site instead of specifying OpenWeb() method.

Use the code below,

SListTemplateCollection lstTemp = oSPsite.GetCustomListTemplates(oSPsite.RootWeb);

Instead of below line

SPListTemplateCollection lstTemp = oSPsite.GetCustomListTemplates(oSPWeb);

Answer 3

You are getting the error because lstTemp might be null. Check if the object is null before getting a specific template by Name.

Answer 4

Seems like "MyTaskList" list template is not included in the lstTemp. You need to debug and see if the line SPListTemplateCollection lstTemp = oSPsite.GetCustomListTemplates(oSPWeb); actually contains what you need.

Can you also try oSPWeb.ListTemplates instead of oSPsite.GetCustomListTemplates()

Answer 5

I got answer. I create list in already existing list instead of myself creating new list.

SPList thisTaskList = oSPWeb.Lists["MyTaskList"];

SPListItem tasks = thisTaskList.Items.Add();

tasks["Title"] = "New task" + DateTime.Now.ToString();;

tasks.Update();
