Arraylist As Repeater Datasource - Can Access From .aspx
Apr 16, 2010
I have an arraylist:
Dim downloadsarray As New ArrayList
downloadsarray.Add(iconlink)
downloadsarray.Add(imgpath)
downloadsarray.Add(filesize)
downloadsarray.Add(description)
I've got an ArrayList bound to a repeater control. In an associated, but separate, area of the page, I'd like to get the first and last item out of the bound control. It's actually a paging element to a table.
I am working on setting up an aspx page using access datasource in web eepression. Access Datasource is having image source information from other resources feed. I am using listview to display all the images. The problem I am facing is that all the images are displaying in different sizes. I tried to customize Layout template by specifying the td height and width but it's not working. Is there any way to autosize the pictures in listview once page is displayed.
i want to create a arraylist which will able to store user info like (username,machineIP,port ) for each user in the list & retrive this data when needed . any one tell me how i can do it or any alternative way without database or xml file.
I am using a repater whose item template is having a dropdownlist. Now i want to access that dropdownlist from a button click event. Here is the code iam using :
I want to add array list in sqlcommand.but i don't no how to pass it. My code is.
ArrayList ProductId = new ArrayList(); for (int i = 0; i < ShipmentPackage.Items.Count; i++) { ProductId.Add(ShipmentPackage.Items[i].ProductVariant.ProductID); } select * from TableName where id= ProductId(ProductId is my Arraylist)
I'm trying to convert some code from VB to C# on a site i'm working on and can't seem to get the arraylist to function properly.
Here is what we currently have in the codebehind:
[Code]....
Which we then call from the page using:
[Code]....
I want to convert this to C# as the rest of the code on the new site is in C# and I'm having problems with the ArrayList. I've got the other parts of the code all converted fine it's just the GetContent Function that isn't working right. Here's what I have:
[Code]....
I got an error on the "objSDR.Item" part of the code saying "SqlDataReader doesn't have definition for Item" and so if I changed this to the code above. Only problem now is I can't call this from the page using the code below as there is no "Item" in the GetContent Function any more
I have a web page where a GridView will be shown with a column of different products and another column with checkboxes. Checking on the checkboxes will be equivalent to selecting the products. The selected products are saved to an arraylist. Then, the user has to click on a button located on the same page to analyze the selected products. On clicking the button, he/she will be directed to another page where a bar graph will be shown. The bar graph will be the result of having analyzed the products. How do I create the bar graph where the products are taken from the arraylist but I can make use of the datasource within the chart control to retrieve more detailed info(such as product sales) from the database, taking into account the products from the arraylist?
I put common code in the app_code directory. I access classes in the code all the time from aspx.cs files by "using" the name space from the C# file in app_code and then referencing the class. Now I want to access a class from an app_code file a aspx file. How do I do this?
I have been trying to call a vb.net function in aspx page how can i do that?. I have done it in C# by
<td><#%GetItemIndex(Container.ItemIndex)%></td> its working fine in C# but in vb.net it says GetItemIndex not declared.
and trying to convert (rptpages is a repeater)
rptpages.Itemcommand += New RepeaterCommandEventHandler( rptpages_ItemCommand1) from C# to VB.net but i dont see itemcommand property in VB.net for the repeater.
Now, let's make it more fun. Let's suppose that there is one or more phone number per name. I feel like I could use a repeater within a repeater to repeat the phone numbers. I could also use a for loop in my asp code. However, the Eval function is the only way I know of to access the current record at runtime and Eval only returns a string and only runs in <%# Eval("X") %>. How can I get the list of phone numbers that is a member of the current record?
I have a situation where I am accessing a database multiple times and I'm wondering if it is necessary.
I have a GridView with a template column with a hyperlink to "Get Results" and on the RowDataBound event I have it check the batch number against the database and see if results exist and then if they don't, hide the link.
So when viewing the page if there is 20 rows in the gridview it is effectively doing 20 queries.
I was wondering if it is a better idea to query the database once with all "batches" and load it into a datatable, then on the RowDataBound event query the datatable. The only issue I see with this is there is currently 40,000 batches and grows daily.
switch(e.CommandName) { case "Edit": //make editTemplate div visible HtmlGenericControl divEditContact = (HtmlGenericControl)e.Item.FindControl ("divEditContact"); divEditContact.Visible = true; break; case "Update": Employee updateEmployee = new Employee { employeeName = txtName.Text: employeeEmail = txtEmail.Text: } updateEmployee = API.UpdateEmployee(updateEmployee); //display lblUpdateConfirm visible to True // so user sees this confirm messge in the newly updated ItemTemplate }
How can I access my lblUpdateConfirm and turn its Text state to visible from inside the ItemCommand, so that when the user sees the newly updated ITemTemplate, the label is showing the "Update Confirmed" message?
I have a GridView inside a repeater, and for all the GridView events such as ItemDataBound, etc. I can't just use the same because it doesn't recognize it. I know I have to use FindControl and type in the ID, but how?
I'm looking to write some script that checks that: The current user of whom is logged in has the correct authority credentials. NB: Script in C# before I continue. To give a bit more background. The SQL DB Table for AdminUsers has a field 'Authority' this is linked to another table (Authority) which has the values/different levels of authority in them. Thus, if aN admin user whose Authority level is just listed as 'user', for example, in the database and wants to edit information that requires 'Supeuser' authority level - it cannot be performed and is redirected to another page. In detail, my particular page, the operation is being done via a ASP Button within a ASP Repeater. Of each record that occurs there is the button that, once pressed, updates the field in the database (in this case for a Guestbook table which has a 'Moderated' field of 'bit/bool' data type, changing it from false to true (or 0/1)). To allow that entry to be displayed on the front-end for public viewing. All this can onyl happen on the basis of, as previously stated, their authority is of the appropriate level. Here is what my attempt was. The outcome of which simply redirects to the 'Unauthorised' page, despite the user logged in having the correct authority credentials.
