Display A Message If The Search Returned No Results?
May 21, 2010
I have this code:
Dim Result As New DataTable
DataAdapter.Fill(Result)
'bind data to visible surname/name grid
If Result.Rows.Count = 0 Then
NoInputBottom.Text = "No Results. Please widen your search criteria and try again"
NoInputTop.Text = "No Results. Please widen your search criteria and try again"
Else
GV.DataSource = Result
GV.DataBind()
End If
I have also tried moving the check to the gridview like so:
If GV.Columns.Count = 0 Then
NoInputBottom.Text = "No Options Selected: Please select your search criteria and try again" NoInputTop.Text = "No Options Selected: Please select your search criteria and try again" End If
When I run the code. the noinput labels do not have value, the null check seems to be failing? how to display a message if the search returned no reults.
I am developing a web form for search capability. The search query should return records from three different tables. How to display these three table records in three different rows. The search query should get the results from Table 1 and Table 2. Table 2 and Table 3 has a parent child relation ship. Which controls can I use for this purpose?
I'm developing a search page that will display the results in a gridview. The codebehind (in VB.NET) uses a SQL command to fill the gridview.
The gridview does have paging and sorting enabled. Once the search button is clicked the initial results are displayed, if the user clicks on a sorted column or wants to advance a page the gridview disappears. Enable Sorting And Paging Callbacks is set to True. Enable ViewState is also set to True.
I am trying to develop a page where I am trying to search a database (MyQSL) and display the data in a table format. Some of the database entries, like category, is stored as integer values, but I want to display the category name in the search result (not the corresponding integer value). I have also another issue, every time I change the dropdown list values (which are having "auto postback" enabled) the <EmptyDataTemplate> is returned. At this moment I am using GridView. But I am ready to change this to any other method, like repeater or whatever...
I want to search record based on Name, ID, Date, Report Type. from same table with one textbox. I can do search with one column how can do it with multiple column ...
protected void Button2_Click(object sender, EventArgs e) { DateTime dt = Convert.ToDateTime(TextBox1.Text); SqlCommand cmd = new SqlCommand("SELECT * FROM Transactions where report_type = @report_type "); cmd.Connection = con;
I need a query to fetch records from data from database based on partial text entered in textbox like search data from College table based on College Name entered in text box. I want that all record containing that College name displayed in grid view.
I have a .Net 4 Chart Control bound to stored proc. For some customer selected queries the chart will be empty. I would like to display a "No data" message in the empty charting area so customers understand why the chart is empty. I haven't been able to find any information about how to do this.
I implemented PreviousPage to get data from previous page for my search function and display the returned data into a gridview. The gridview's allowpaging is enabled, but every time I go to next page, my previous page data is lost... how can I resolve that?
As a newbie coming from a Java background with tag libraries I wonder if there is a simple possibility to render areas depending on backend values.For example if I have search form I do not want to render the table for the search results as long as the user hasn't pressed the search button. Of course I can iterate over the model containing an empty list but this does not allow to suppress rendering the whole table.Using web forms I would just control the visibility of the affected tag(s) in the code behind file but how do I do this with ASP.NET MVC?Can I use a partital view for a case like this? But I think I would have the same problem. How can I determine if a partial view is rendered (e.g. the whole result table with header)?
i have some text boxs in a page and in the same page there will be a table 'grid' like for holding the search result.When the user start editing and of the textbox above, the search must start by sending all textboxs values to the server 'ajax', and get back with the results to fill the below grid.
Notes:This grid should support paging, sorting by clicking on headers and it will contains some controls beside the results such as checkboxs for boolean values and links for opening details in another page.
I know many ways to do this some of them are:1- updatepanel around all of these controls and thats it "fast dirty solution"
2- send the search criteria using ajax request using JQuery post function for example and get back the JSON result, and using a template will draw the grid "clean but will take time to finish and will be harder to edit later".
3- ....My question is:What do you think will be the best choice to implement this scenario? because i face this scenario too much, and want to know which implementation will be better regarding performance, optimization, and time to finish.
I am having problems with the following. On debugging I find that when strKeywords = '', reader = "System.Data.SqlClient.SqlDataReader". However, as soon as strKeywords takes the value of anything else, reader = nothing. But the stored procedure handles the arguments fine, so I am very confused!
i m using three web services in my project ... while Webservice1 returns data in a set of 50 records at a time .. the other 2 webservices return the entire resultset .. the consolidated results(20 per page) are to be displayed in sorted fashion...now the query is to find the best way to retrieve the data from the 3 sources while applying the sorting across the consolidated results. I have developed some code for this but am looking for something better ..
Note: You may not need to read the whole thing to know what's wrong... skip down to the part about the 3 scenarios if you'd like. Only read the begin if you'd like some background info on how I've tried implementing this and where the errors occurred.To begin with, I'm trying to retrieve a list of Clients stored in the CRM_Clients table for a given callerId.I retrieve the clients from my Controller with the SelectLiveClientsForCaller method. The message is then passed on to the DAL through the static Instance method in the DataProvider class:
public List<Client> SelectLiveClientsForCaller(int callerID) { List<Client> results = new List<Client>();
Trying to figure out how to handle data returned for a site search from a description field. I don't think I want to display all the text from the description field, but I also don't want to "chop" a word in half. How do I get the first 100 characters, plus a few extra letters if needed to prevent a word from being chopped in half. In some cases, the description field is less than 100 characters, so all the text will be displayed. However, if the description does need to be chopped at 100, I'd like to finish the word and add ... to indicate that there is more text.
I am trying to make an asp site where someone types in a search term, then google (or any search engine) is searched for that search term and the resulting urls are compiled into a database.
Is this possible? How would i access the search results?I have seen other websites that do something similar - for example on one site you type in your search term and your website, and it comes back with which page your site is for that search term - how does it access the search results?
