Hello.
I tried to send javascript - object to Webmethod, but I get error when send arrays.
Here's my JS-code:
var categoryIDs = $("#" + ddlCategoriesCliendID).multiselect("getChecked").map(function () {
return parseInt(this.value);
}).get();
var tagIDs = $("#" + ddlTagsClientID).multiselect("getChecked").map(function () {
return parseInt(this.value);
}).get();
var authors = $("#" + ddlAuthorsClientID).multiselect("getChecked").map(function () {
return parseInt(this.value);
}).get();
var data = {
SearchText: "text",
SearchIn: 1,
CategoriesIDs: categoryIDs,
TagsIds: tagIDs,
AuthorID: authors
};
data = JSON.stringify(data);
$.ajax({
url: 'Search.aspx/SearchNewsData',
data: data,
dataType: "json",
type: "POST",
contentType: "application/json; charset=utf-8",
success: function (result, status) {
CreateGrid(result);
}
});
But when tried to send in the server I saw "Error 500". I tried with different parameters, but without success. Can you help me, which types should be parameters in C# - WebMethod?
I tried with these:
[WebMethod]
protected static void SearchNewsData(string SearchText, string SearchIn, string[] CategoriesIDs, string[] TagsIds, string[] AuthorID)
{
}
[WebMethod]
protected static void SearchNewsData(string SearchText, string SearchIn, int[] CategoriesIDs, int[] TagsIds, int[] AuthorID)
{
}
[WebMethod]
protected static void SearchNewsData(string SearchText, string SearchIn, List<string> CategoriesIDs, List<string> TagsIds, List<string> AuthorID)
{
}
[WebMethod]
protected static void SearchNewsData(string SearchText, string SearchIn, List<int> CategoriesIDs, List<int> TagsIds, List<int> AuthorID)
{
}
[WebMethod]
protected static void SearchNewsData(string SearchText, int SearchIn, string[] CategoriesIDs, string[] TagsIds, string[] AuthorID)
{
}
[WebMethod]
protected static void SearchNewsData(string SearchText, int SearchIn, int[] CategoriesIDs, int[] TagsIds, int[] AuthorID)
{
}
[WebMethod]
protected static void SearchNewsData(string SearchText, int SearchIn, List<string> CategoriesIDs, List<string> TagsIds, List<string> AuthorID)
{
}
[WebMethod]
protected static void SearchNewsData(string SearchText, int SearchIn, List<int> CategoriesIDs, List<int> TagsIds, List<int> AuthorID)
{
}
[WebMethod]
protected static void SearchNewsData(string SearchText, int SearchIn, object[] CategoriesIDs, object[] TagsIds, object[] AuthorID)
{
}
[WebMethod]
protected static void SearchNewsData(string SearchText, int SearchIn, List<object> CategoriesIDs, List<object> TagsIds, List<object> AuthorID)
{
}
But without success.
Thanks.
