Forms Data Controls :: Accessing A Checkbox In A GridView?
Feb 10, 2010
I have GridView control with a checkbox in one of the columns. When I click a button to submit, I want to see if the checkbox is selected, but when I do, it only gets "Yes" for Label but false fo Checked. I know I am accessing the column because I get the Label. Wha tam I missing?
I want to select all checkBox in Gridview when click to header checkBox.I have created design such that CheckBox is not available to header of Gridview.It is in other table. Below is design of gridview.
I have a GridView that I was previously populating via an ObjectDataSource, and this code was working perfectly (ie, when the checkbox was checked Checkbox.Checked = true):
From what I understand within the Gridview Object you can have many datakeynames.
I have the field like this DataKeyNames = "id1, id2"
However, i don't know how to access the DataKeyNames individualy. For example. How do you access the first ID for the for a given row or the 2nd ID for a given row????
I currentlly am trying to get a bit value from a specific cell, i can get a text value from text cell but i cant seem to fiqure out how to access the bit value. This is on a dgvRowCommand event so im using datakeys to access the row and a column index for the coloumn like so.
This works if im trying to get a text value but obviously a bit value isnt text and thus does not return anything, How would i access a bit value in the manner above, or if it is not possible that way what other alterntives are there?
I have a Gridview X in which there are 6 columns(5 template columns that are text boxes and 1 bound field). The user has the option of changing the value in the text boxes annd saving them. There is one more GridView Y that displays DB values(all 6 columns are bound fields). Initially X will show the values that being shown in Y, and when user changes the values in Y,he should be able to save it. If we are trying this using OnTextChanged event of asp:Textbox, there is a postback everytime the user makes a change in any of the textboxes. Instead i want it such a way that all the changed values should get concatenated together and should be sent to the DB.
In a page, there is a lable called lblTotal and a gridview with 3 columns; Name, Percentage and Amount.
Name and Percent are values that come from a database. Next I need the caluclate the Amount field. The Amount field should be set by taking the Percentage column value in each row, against the value in lblTotal and displayed in the Amount column
So for example
If the value in lblTotal is £200 and the dataset in my gridview looks like this...
In my application Iam using GridView, in this there are fields (Quantity, Price, Amount) the user can enter Quantity Field value which is a template field (textbox). Iam calculating Amount(Quantity * Price) using Javascript and assigning to the Amount Column cells as below
Gridviewcell.innerText=Quanity * price.
and when user clicks on the Save button I want to add these details of Gridview to the database.
when I try to access the values of the gridview using below code
For i=0 to GridView.rows.count-1
GridView.Rows(i).Cells(2).toString ( for Example)
Next i
It is not displaying the changed value instead it is displaying the default value before calculating the amount.
Before implementing the Javascript part, I had done this in the code behind and it was working fine... Now I just dont want the page to get load so I used javascript.
able to access the value of Gridview cells which are assigned using Javascript.
So I thought that you could use id="name" and access this just like an ASP control such as <ASP:Checkbox
or <ASP:Label etc. My code continues to caugh and state object not set to an instance of an object when I uncheck my checkbox
Line 741: ElseIf Not Me.CheckBox1.Checked Then Line 742: Dim row As GridViewRow = gvLink.SelectedRow Line 743: Dim recip As HtmlAnchor = TryCast(row.FindControl("recip"), HtmlAnchor) Line 744: Response.Write(recip) Line 745:
Is there a way to access the updated text property of a TextBox which is inside a GridView cell when a Wizard controls next or previous buttons are clicked? I have a requirement to not use the edit and/or update buttons on the GridView row. Therefore, I am trying to figure out a way of grabbing the updated values of each TextBox of the GridView on the PostBack. Furthermore, these controls (i.e. Wizard and GridView) are within an AJAX UserControl.
I have a gridview which has autogenerate Columns Property "TRUE", and i'm dynamically binding this gridview with columns with sql database dataset. there is no data in sql but i am successful in showing blank gridview on form, now i want textboxes in gridview attached with each column, so i wrote code in RowDataBound which generates textbox automatically and assigns ID to each textbox, nw i want to insert that data from textbox to database but i'm not getting text which is entered in those textboxes, as i am accessing that textboxes using findcontrol and passing the id like gridview1_ctl03_text0. but i''m not getting any value from textbox?
In short i want to access auto generated textbox (with out any id predefined ) values from footer of gridview
I've been searching all day for a solution to this, but nothing has worked.
Here's my scenario: I'm binding the gridview to a datatable. One of the columns is a textbox that will accept user input.
When a "submit" button is clicked, I need to loop through all the rows, get the textbox's text, and add them all together. Simple, right?
I've tried the following (this is on the "submit" button's click event):
[Code]....
The itemtemplate looks like this:
[Code]....
The txtDays.Text property is ALWAYS empty. UNLESS I assign it a value w/in the control. But then it's ALWAYS that value. I need to get the value of what the user enters.
I am using a list of objects as a datasource and passing the object into a user control. I use the code outlined below
[code]...
When I try to access the object this way, it's null.
Funny thing, I can access the user control and all the control data in the user control, but the object (both in the gridview and passed to the user control) are null.
Iam using a radio button in a Gridview. I want to check whether it is checked or not. If it is checked i want to pass one value or if it is unchecked i want to pass another value. But even when i checked the radio button, it is still showing unchecked in the Debugger. How to check whether it is checked or not. Following is the code iam using:
I have Grid view on my WebForm, a Checkbox placed in a Grid view,i have 70 field/column values right below grid view,when ever i select the GridView Checkbox ,entire record should be displayed in field/column values.How can i acheive this please provide
I'm a little bit confused. I'm trying to pass in some values to the associated database table from a gridview.I have a databound gridview fetching values from a database, on each row a checkbox is generated to each item in the list. For exapmple, the gridview fetches data from the table "Interests" and prints it out on the page, and the visitor is supposed to check in those checkboxes that corresponds to his/hers personal interests.When clicking submit, the Table UserInterests in DB gets the values:
UserID = 1 (gets a unique ID from a previous step) InterestID = 45 (Shopping) UserInterestID = (auto increment)
What i need help with is how to check if the Checkboxes is checked or not, and how to pass in the true or false to the db.I have read Step 2 in this tutorial, and it seems like my solution will be somewhat similair to this:http://www.asp.net/Learn/data-access/tutorial-52-cs.aspxKnow it's a tricky question when not knowing the structure of the project, but i'll be glad for some pointers and tips!
