Forms Data Controls :: Hide Submit Button If Datalist Control Is Empty?
Jul 16, 2010
I would like to hide a submit button if a DataList is empty. I don't really know the code. If you submit an answer please show me the code also. I have to do it in VB.Net. I googled and found the following code that I place in the code behind under the Page load event.

Dim dv As DataList
dv = SqlDataSource3.[Select](DataSourceSelectArguments.Empty)

The code I have written is working fine but when user is logged in then Only one products hyperlink text changing. I want change it to all hyperlink text to view more when user login

I've created a stacked bar chart - so there are multiple series in a line. The series display the value, but when the value is 0 I don't want the value to be displayed because if there are multiple 0 value is starts to look like 0|0|0|0 i.e. not very nice on the eyes. I'm wondering if there is a way i can say if the value of the series is 0 dont display the value.
I want to show a message when there's no data in my datalist. I found the following, but, I get an error on the bool. If you have another way to do this, great, but, I'd also like to try to do it this way as a learning experience.

I have a databound Gridview (with a LINQ datasource). The gridview displays questions from the SQL DB to the user. I've inserted a radio button list into the gridview with 3 horizontal radio buttons with fixed values of 1,2,3 for the user to select. I have a question ID, a tempuserID, and AnswerValue columns set up in the database. It all works nicely.
After the user selects radio buttons, I would like for them to push a button to submit the QuestionID, the associated Radio Button Value (AnswerValue) and their tempUserID into the DB. How do I do this? I'm not sure what to do next and what VB/LINQ code to put in the code behind file in the button click event handler. I'm also not sure on what to use for the tempUserID, can I use the sessionID? I'm using VB and here's my code:
I am new to using ASP.NET and I am using a datalist to represent the data obtained from querying a database.However,I am facing 2 issues:
1) If the string returned after querying the database is too long,the datalist is displaying the long string as it is which is not looking good.I am using Eval to fetch the data from the database for the sake of displaying.I need to have some page breaks so that the information fetched is presentable.
2) While repeating the datalist I want to hide all the columns except for 1 column whose value are unique.Upon searching I found this link: http://www.programmingknowledge.com/DataList.aspx but the code is in VB and I am not familiar with it.I am familiar with C#.
I am inserting the front end code for my datalist.I also want to know if datalist is the best control to present the data from the database.
I have a repeater control having columns in it.When I bind the control to a data source then some of the columns become empty when there is no data associated with it.I want to hide the column if there is no data associated with it.I was trying to implement a solution given in this thread:

However,I am not sure how to write the logic for hiding and showing the placeholder.I have written some code for the same but that clearly doesn't work.The following is the .aspx as well as the code behind which I am using:
I have One DataList in their three columns ID, FirstName and LastName, when I select ID then I want to access the value of ID how to get the value of selected ID.
I have a datalist bound to a sql source having two columns: Name and Description. The datalist contains a "Show Description" link as follows on clicking on which it calls the javascript which shows the description div.
[Code]....
The asp.net page source for itemtemplate of the datalist is as follows.The problem is that since the div id "Description" is applicable to multiple records, no matter I click on whichever "show details" link, the description of first record in the datalist is shwon and hidden since its the first div encountred by the javascript. In other words, I want a way to show/hide the description of each record in datalist indivigdually. [Code]....
I have a gridview and when i click on the edit button i will get the modalpopup window which is having a popup window i want to update the data in that details view and refresh the data into gridview also.
