I have a gridview that is a directory of people with about 50 pages
How would I make another gridview that had first row with 26 columns, 1 for each letter of the
alphabet and second row with the first page that has last names that start with that letter.
I've already searched to no avail for an answer to this question:is it possible to dynamically alter the page size in a paged gridview based on data in a particular column?In other words,let's say I get data from a table that lists students enrolled in a particular course.If there are 10 students in Course "A," then I want page 1 in my gridview to show 10 records.
If there are 15 students in Course "B," then I want page 2 in my gridview to show those 15 records,and so on.I imagine that this could probably be done with a master-detail kind of set up,but let's say for the sake of argument that I don't want to go that route.
I am trying to determine the number of pages in a custom paged control I have Built
there are 46 records and I am trying to get to the exact number of pages when there are 5, 10, 25 items per page etc...
at 5 items per page I should have 10 pages
and at 10 items per pages I should have 5 pages
but my code returns values that cannot use.
this is my code:
[Code]....
those are values I get.
When maxrowperpage is 5
pagecountConverted is = 9
pagecount is = 9
When maxrowperpage is 10
pagecountConverted is = 5
pagecount is = 5
how can I get a correct quotient?
I need to make a large Ebay-style list of listings (think of the page that comes up when you search for something in Ebay, with a photo, title, one-line description, price, that's paged, and sortable). My limited experience with DataGrids in the past always resulted in what felt like a sluggish page to me, but I'm not sure if it would have been faster if I had pieced it together with a data reader instead.So I'm wondering before I even get started, what is the fastest / most efficient way to retrieve and manage this data.Is it more efficient at runtime to use a DataGrid, or to write the paging and sorting in more manually and use a DataReader, or another way?Ebay manages to get thousands of listings to display very quickly, but they've obviously got a lot of manpower to squeeze every last bit of performance they can out of the site, and good high-powered servers.
View 5 Repliesi have page which is derived from nested master page. Below is the hierarchy
Master.Master
Master2Column.master
Bronze.aspx
The aspx page is derived from master2column and which in turn is derived from master.master.
Now i need to find a control in bronze.aspx page from master.master.cs page. This is where i am getting lost.
My master.master has the contentplaceholder1. Below is my master2column

And the maincontent is in bronze.aspx page. Now i need to find a label called lblTo.
I tried this one

and few other options too. But still i am getting "Object reference not set to an instance of an object".
I am doing a social portal over here. And i have 2 gridviews..
First Gridview which displays all the latest updates a user made and the second gridview which displays the comments made to the latest updates and it is place in the itemtemplate of the first gridview.
The problem now is.. how am i going to locate the 2nd gridview inside the first one? For window components u use FindControl.. But what ever gridview?
Page B - loads slowly and needs to do some CPU-intensive operations on the web server.
I noticed that when someone is loading Page B, then Page A also loads slowly. This is even worse if multiple users are loading Page B at the same time. Page A won't finish loading until Page B is done.
Is there a best practice for making sure that Page A can still load quickly? Maybe a config setting or IIS setting that I need to change from its default? With 2 users loading Page B at the same time, the web server CPU usage only gets to 30% so I suspect it might be something I can tweak with the settings.
I am trying to get the highest, lowest and average values from displayed gridview and then highlight the numbers. I had this code working, but now, I don't know what's going on.

View 1 RepliesI have a gridview where I in codebehind add a templatefield
[Code]....
In my update command when i try to find the "Result" textbox I get a null object
[Code]....
In the gridview there is another templatefield "Name" that consist of two boundfields("Firstname" and "Lastname") This column is added in the design phase and not in the codebehind.I don't have any trouble finding these controls using the ID added in the markup
[Code]....My issue is with the result column that I add in codebehind.
I have an object data source control. and to insert the control I add the object to the database then call databing on the gridview the DataSource control is bound to.
My question is - how would I know where the newly added row is? I can'y go by id, because the dbase creates the id.
I'm thinking maybe last data key, but based on the sort that would be accurate.
How to find the client id of a cell in GridView that is in edit mode. I need to attach javascript to the cells of the row that is currently being edited.
View 1 RepliesGlobally i want to find a textbox which is in a gridview such that i can use that variable in any of the events.
Is that possible in .cs file or if not how can we retreive the variable of a textbox in to a function after finding the textbox using javascript in .aspx page .I tried to find a control in .cs file but I couldn't get it.
Im having trouble accessing controls inside the gridview. I have a formview control on a aspx page and inside this formview i have controls that are bound to a datasource. Which works hundred percent. Also inside this formview i have a gridview which i have created my own template. Gridview1 has 3 columns with textboxes in each column.
Column 1 - LogDate
Column 2 - LogBy
Column 3 - Number dialed
Now this is what im trying to do. I have a dial button inside formview1 along with 4 textboxes which has telephone numbers in it. When i click on the dial button i want the time to be populated into Textbox1 which is inside gridview1 and at the same time Textbox2 to be pupulated with the Username as well as the number must be populated into Textbox3 inside gridview1.
I am using Asp:TemplateField in gridView. I have only ONE TemplateField as follows
[Code]....
I want to find all the textboxes (when grid row is in edit mode) using some kind of loop. I don't want to find the TextBoxes by their names like e.row.findcontrol("..");
I did Response.Write(e.row.controls.count), it show "2". How can I find textboxes without using names
almost typical master-detail scenario except the 'detail' data I want to display below the gridview will be coming from both the table that is bound to the gridview (master) and a related table.
simplified example: tableMain with field1, field2, field3 bound to master gridview. I need to select a row from the master gridview and have a form display below with field4 and field5 from tableMain, as well as all fields of tableDetail where field1 of tableMain equals field1 of tableDetail.
Is this what a 'formview' control is for? or do I just arrange my own controls to accommodate the data? Would a formview work considering my source will be partially from both the main table and the detail table? This is one of the scenarios were I know I could come up with something using none of the databound controls (except the master gridview), but I want to use the controls provided when it makes sense to do so, and utilize their benefits etc...
I need code for gridview context menu like edit, delete,cancel
