I have anested ListView control. I also implemented a jQuery to automatically expand the TextBox control inside of the nested ListView Insert Template. The problem is, when the Textbox expand, the outer ListView control is not; therefore, the Textbox control expands underneath the buttons of the outer listView control. How do I expand the outer ListView control as the nested ListView textbox is automatically expand? One great example is in Facebook where if I add a response comment, it'll automatically push any comments below mine down. If nested Listview control is not the best way to do this, what are my options?
View 8 Repliesprovide an example to do that... "Hide column if row is empty" in Databound()
datasource could be .1
coulmn: id-value1-value2-value3
row: 1-4-3-NULL (output: hides row value3) because the value is NULL
.2
coulmn: id-value1-value2-value3
row: 1-4-NULL-NULL (output: hides row value2,value3)
i have a grid view myGridView. I populate this gridview in the page load event as:
myClass newObj = new myClass();
myGridView.datasource = newObj.getItems();
myGridView.databind();
Now I wanted to hide some of the columns of the grid view. How I can do that?
I've programatically created a DataView item by adding columns and rows to a table in the class file. Then I add that to my webform using a GridView. I'd like to hide some of the columns so that the end user doesn't see them but still be able to access their values.
How do I do this programatically? The table.Columns.Count returns the actually number of columns. Somehow when it converts into a DataView, it is only returning 1 column.
//From class file

//From webform

In this example, I want to hide the ID column.

I am facing a problem with Gridview control. I have created a Gridview1 which is having 3 button column that has been added at design time and some column can be added through the Datatable at runtime. At Design time GridView1 has 3 button column
At Runtime I do GridView1.Datasource=dt; //Now my gridview is having 7 columns i.e. 4 more columns added through datatable.
I can easily display that GridView1 on webpage but I dont want to show some column that I added through Datatable to the user.
When I try to hide that column, I get error like Index out of bound exception but when I hide button column I can able to do that easily.
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.
