View 6 RepliesI was hoping someone could lead me in the right direction in creating a search form with the data being displayed with paging. My background is ASP classic and I would like to know the best approach in acheiving this with MVC. Maybe if we could take the Movie Library tutorial and add a search function to it, so I can understand from the ground up. Basically, I'd like to see a couple of fields for the movie title and director in a form, with a search button. The data in these fields would the be used as parameters for the SQL to query the database and then display the data in the respective view with paging. Whats the use of a database if it cant be searched by the user? Obviously being an asp classic dev, I'm not familiar with C#. I will go down this road eventually, but I'd like to go down this path 1st.

It looks that the old SqlHelper class from the Microsoft Enterprise Library has been mostly replaced by the Database class which is included in the new Enterprise Library version 5.
I have a very simple and trivial example:
using Microsoft.ApplicationBlocks.Data;
private void PopulateCheckBoxGroup()
{
const string strConnTxt = "Server=(local);Database=DataBindTests;Integrated Security=True;";
const string strlSql = "select Technology from PreferredTechnology where ParentId = 1";
CheckBoxList1.DataSource = SqlHelper.ExecuteReader(strConnTxt, CommandType.Text, strlSql);
CheckBoxList1.DataTextField = "Technology";
CheckBoxList1.DataBind();
}
from years go i use "SQL Helper" class that exist in Microsoft Application Blocks for .NET and i used it for about 1 year in many projects but after that many senior recommend me not to use as it's have many problems in big projects and i let it but know in a new company they want to use it in a projects ... Could any make his recommendations about it / and if it's really excellent to use it have already issues ?Is there any other good solution rather than SQL Helper ?

I would like to use an eval stmt to return a true/false for the visible property of a HyperLinkField. IF clientComment exists, I would like it to return True, if clientComment is null or "", then would like it to return False.
By default I noticed it already will not show the hyperlink if clientComment is Null, however the bug I'm running into is if the client enters a comment but then later deletes it so it's not null but blank, or "", in which case the HyperLinkField will incorrectly display. Here's my attempt so far but I'm obviously hitting a wall:
Visible='<%# Eval("clientComment")==Null or =="",False) %>'

I've tried to work around it but can't fix this
I created a new page in an existing project. The existing pages are still good, but the new page is having problems at runtime. The problem is that controls are not recognized and throw a "object reference not found" error. I even tried Page.FindControl and that didn't work either. This is only happening with this page. The controls are recognized at design time, and are not recognized only at runtime.
The controls were copied from a regular Web form into a content form with a master page. They worked fine when in the regular web form. Could that be the issue?
I tried creating a new page and moving the controls over, but that didn't fix the problem. I also tried deleting the designer file and recreating it (using convert to web application) but that didn't resolve it either. I'm out of ideas here. Here is the page directive and the first control that is not recognized.

I need to access controls of aspx page and usercontrol page through the external .js file. I created a global varaible in the aspx page
<script language="javascript" type="text/javascript">
var loadPanelID = "<%=ajaxLoadingPanel.ClientID%>";
</script>
Now I pass this value in the onclick event of button click (Let the funtion name be Fun(loadPanelID) ) . The controls is recognised in the .js file. Everything is fine till now. Now i need to call the same javascript method Fun() from the button click of usercontrol.
<script language="javascript" type="text/javascript">
var loadPanelID = "<%=ajaxLoadingPanel1.ClientID%>";
</script>
I have ajaxLoadingPanel1 in the usercontrol and I have defined global variable as in the first one in ascx and passed that value to Fun() method. But this time it gives error called "loadpanelID" is undefined.
I want to dynamically create asp textbox objects (as well as other types) with id's named sequentially up to a number the user decides but I'm having a problem getting my code behind to recognize these dynamically created objects. In "div1" below I manually create the objects and I have no problem getting the values in Sub cmdSaveDiv1Info_Click. My dynamically created code generated in Page_Load routine is identical to that in "div1" except for the textbox ID's yet when I try to retrieve the values the same way in cmdSaveDiv2Info_Click I get an "object reference not set to an instance of an object" error on the "Dim d2Year as String.." line.
