Forms Data Controls :: Finding The Highest Value In A Gridview
Jan 6, 2010
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. It does NOT give me the correct values!!! What's wrong? For simplicity I just give the code of getting the highest number. Here is my code:
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?
im trying to locate the row of my gridview when i enter the rowID in textbox and click on the Go button.
if my grid contains 40 items(rows) if i enter some 23 it should go to particular page(my page size is 10 records per page so 23comes 2nd page 3rd recod) and find that row and highlight it with some color.
im find row count as follws
[Code]....
with this code im able to find only with in first page im able to locate the record.
i mean if i have 16 records it locating 6th record of 1st page but it has to go to 2nd page 6th record.
Is there a way to find out which column is selected in the Gridview row command? When I click on a gridview row in a specific column, is there a way to get the column index of the selected row?
I'm using this code to access controls inside a gridview using javascript:
[code]....
Thing is that for some reason it doesn't locate Validators. If i add the line - alert(sid) , it will show me all the Id's of the controls inside the GridView except for validators.
I currently have a gridview that has autogeneratecolumns = true. Right now, I am trying to find all the column names of a given table. Since auto columns arent part of the columns collection, Grid.HeaderRow.Cells[i].Text does not work. I have also tried
I am tring to write some custom filters for a gridview and want to base the filters available based on the datatype of the Columns in the GridView. How would I go about determining the datatype of each column?
I 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.
Globally 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.
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 have a gridview with a template field column. In the edittemplate of that column i have a textbox. In the next column of the gridview i have a button. When i click the button i need to find the value of the before mentioned textbox. I do it like this:
gridview1.selectedrow.findcontrol("textbox1"). This sometimes work just fine and without a problem but sometimes it seems it can't find that control and throws a null reference object. The error it's random like i said, sometimes just work and other just don't work...
