View 5 Repliesi 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 have the following returned in my store proc:
Key, Name, IsReadonly.
What I would like to do is show only the Name and IsReadonly and hide the Key field .
I think u can use a it as a Date Key or something because i then want to delete a record (using autogeneratedeletecolumn)and use that Key in the where clause.
I found this code and tried to implement it in my project. But before running, I got few question. What I want to do is able to delete 1 row each time I click on a button or link.
1. Where is the firing event comes from?
2. Do I need to add a button or link each row (another column)?
3. How does the following code works?

View 23 RepliesI have a dynamically created grid view in the load even of my web page. I am setting its data source at run time like
gv.datasource = someObject.getItems();
gv.dataBind();
Now I wanted to hide, that is to make some of the columns visible false.
First how can I do that, Second should I write the code in the same page_load event or I should write the code some where else, cause when I add this line of code
gv.colums[0].visible=false;
an exception is produces "Argument out of range"

View 3 RepliesIt happened to add an extra Gridveiw Header in row_databound event , It did worked fine on !Postback but disappered on Page.Postback . Quick google search guided me to move the event to Row_Created event and every thing is okay .
Can any expert post some pointers , differnces between grid row_created vs row_databount with some sample table data created dynamically behaviour of both the events in !Postback and page.Postback .
I am doing a online web application whereby user is able to enter in new template as well as search for template. The Add template is located outside the grid view and if user clicks on the button, it will load the grid view that is populated with data as there is a row of empty fields at the bottom. However when I click on the Add Template button, the grid view does not appear.
This is my business logic that I used it to search for records as well to click on the Add Template button to add in new records:

View 4 RepliesI have a grid contol that allows delete what I would like to have is someway to say Are you sure you want to delete?I found this code online, and tried it but it did not work, Do I need something more some behind code maybe?Here is what I found online:Adding 'Delete Protection' to controls If you use a control set up to allow Delete, the Delete button gives a straight delete without any warning, which can be dangerous.To give a warning dialog box, add an OnClientClick event to the Delete button, as follows.
<asp:LinkButton
ID="DeleteButton"
runat="server" CausesValidation="False"
CommandName="Delete"
OnClientClick="return confirm('Are you sure you want to delete this record?');"
Text="Delete">
</asp:LinkButton>
Here is my code: You can see where I added the code from above.
<ItemTemplate>
ID:<asp:label id="IDLabel" runat="server" Text='<%# Eval("ID") %>' /><br />
Name:<asp:label id="NameLabel" runat="server" Text='<%# Bind("Name") %>' /><br />
Destination:<asp:label id="DestinationLabel" runat="server" Text='<%# Bind("Destination") %>' /><br />
OutDate:<asp:label id="OutDateLabel" runat="server" Text='<%# Bind("OutDate") %>' /><br />

View 4 RepliesI am interested in building an intranet document management system to be used from Internet Explorer using ASP.net, VB.net, and MS SQL Server but have no experience in doing a project like this. Supported file types would be txt, pdf (from scanner or imported from file system), or jpg. What concepts I should look at researching/learning about to build the system in a way that files will be stored as small as possible, retrieved and displayed quickly, and secured. The users would be spread out over a regional area covering 4 states.

I am working on ASP.NET 4.0 application.I want to bind the data in a datatable to a grid control and i want to do some formatting. I want to merge the cells or hide the cell border in the first three columns (Merge every 5 cells in a column). And Vertical align the text to center. Also i need row border at the end of every 5 rows.
For example, If i am binding 10 rows to the Grid i need row border only at the end of 5th and 10th row. And merge every five cells only in the first three columns. All the other columns should not be changed. I also want to change the background color of the cells in all rows based on the value in that cell. How to achieve this in ASP.NET 4.0 and which control can be used to display in this format?
