Forms Data Controls :: Accessing Gridview Cell Values?
Oct 2, 2010
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.
My gridview has a dropdownlist when the user clicks "Edit". my question is: How to I retrieve the value of the cell that contains a dropdownlist (when the user clicks on "Select")?
I am able to retrieve the information from the cell that has a textbox (textbox is displayed ONLY when the user clicks on Edit). But when I try to retrieve information from any cells that has a dropdownlist (dropdownlist is displayed ONLY when the user clicks on Edit), it comes up blank.
In order to retrieve the cell I have used the following below:
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?
So I have a gridview control and I am binding it's datasource dynamically base on a dropdownlist. The gridview contains autogenerated columns with auto generated edit buttons. The datasource binded to the gridview is IQueryable<T> where T will be different for different datasource.
My detail problem is below:
A GridView binded to datasource dynamically with all autogenerated columns. When user click edit link, it will display value in autogenerated textboxes.
When user click update link, I am able to capture the user entered value in the textboxes in RowUpdating event, then pass those values to Linq update function to update the database. Now, the problem begin when I try to dynamically add validation controls to each editing row. In RowDataBound event, I am checking the editrowindex then adding validation control to gridview cell and pointing to cell.controls[0] which is the textbox control when the row is in edit mode, I am dynamically setting the textbox control id so that the validation control can set controltovalidate property. The validation control works, but the updating function is setting everything on the grid to empty string.
I am check the textbox text value in the loop, which returns "" for all cells except the id column. It was returning the correct value before I add the validation control. I guess since I added the validation control on rowdatabound event, will it rerender it's own autogenerated textbox in edit mode so that the text value of textbox no longer available in rowupdating event?
Is there a better or correct way to get the cell textbox value? I am using ((TextBox)dc.Controls[0]).Text where dc is DataControlFieldCell in rowupdating event.
i want to show selected row of gridview into textbox then we can change these value then we click update button then these value add into selected row., this row show the update value not previous using jquery . following my code.
<script type="text/javascript" src="~/Scripts/jquery-1.10.2.js"></script> <script type="text/javascript"> $(document).ready(function () { // function Edit() { var par = $(this).parent().parent(); var id = par.children("td:nth-child(1)"); var name = par.children("td:nth-child(2)");
I have uploaded a excelsheet to datatable and that datatable is bound to gridview.there is a save button present,i want to click the save button and all the gridview data will save in database.but that gridview has no boundfield or templatefield.
I have gridview, and in this gridview, I insert a new row dynamically depending upon a value from the database all the way down the table. Even though this is all working well, I need to access a number of controls that I added to the inserted row. Namely, a checkbox and label. When I try to access these controls, I am getting an error message - object not set to reference. Then I tried saying "Gridview1.Rows[rowIndexVal].Cells[1].Text = myTextVal", but what this does is to insert the value on a different row.
Therefore, I have two problems, which I am really desparate to try and solve:How do I access the correct row and control that I have added to my inserted row, andBecause I have a checkbox control on my inserted row, which has an event associated with it, how do I get the selected row the user clicked. When I try doing this using FindControl, I always get a row index of zero.I am using Table object and TableCell to add a new row dynamically to the gridview, and then using ColumnSpan to make it fit the number of columns in the gridview.
I copy in a DataTable a GridView to display this GridView in a another page. It works but the gridview's content is not encoded in UTF-8.
This is the code which copy the gridview in a DataTable :
protected void ButtonDisplay_Click(object sender, EventArgs e) { // On copie dans un DataTable toute GridView filtré DataTable dt = new DataTable(); for (int i = 0; i < GridView1.Columns.Count; i++)
How do i change the name column text the current row when the selected index of drop down is changed? ex:first row is mudassar khan and belgium, when i change belgium i want mudassar to be replaced to a name which i fetch from database....
I have a grid view populated with some data included bit fields and I made an export to excel function For each row i need to check the cell with the bit value to change the cell color, but the cell is always empty, even if is the field is set to False or True. foreach (GridViewRow row in gv.Rows)
I'm having a weird problem where the GridView cell that I'm programmatically updating turns grey, and throws a null error when attempting to save row. I have been searching all day and have not been able to find a solution. I'm guessing there is a problem with my code, so here it is:
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
I am having gridview and i have check box for each row. There are 2 buttons ,accept and reject outside the gridview. If I click accept button, all the checked rows fields value should change to accept and if i click reject button all the checked rows column value should change to reject. There are 3 columns only one column will change.
To start with - I'm using VS 2008/.NET 3.5 and working in a company-provided template that leaves me restricted to some/many settings that go beyond the body of the page itself. That said, I need to create a page that will display data from individual cells in a database table that, when lined up would look like a normal sentence. Based on certain criteria I would have certain sections of the sentences hide (ex. if it contains a key phrase or if it's empty).
I've seen a method in which Labels could be used to achieve this effect, where I would assign it the grid coordinates of the cell in a table, but I could never get it to work. I've been successfully connected to the table (LINQDataSource) but still have a blank canvas without this fundamental display technique as that will be all that's in it.
I have a datagrid whose columns are autogenerated (based on the results from an SQL SELECT query). However, I need to retrieve values from certain cells across the datagrid, using the following code to step through the results.
[Code]....
I need to specify all my columns using TemplateField?
I want take value from gridview when Linkbutton from gridview cliked on link button clicked event.my code is
Protected Sub LinkStudentID_Click(ByVal sender As Object, ByVal e As EventArgs) ModalPopupExtender1.Show() Dim Val_StudentID As String = "" Dim Val_class As String = " Dim linkbtn As LinkButton = DirectCast(sender, LinkButton)
Currently I have a grid view with few rows of data & edit and update for each row but I want it to be done on a single click with w external edit & save button how can the functionality be performed.
i need to do a pop up for every cell in gridview. The moment user click on the cell on gridview , a pop up pop up and showing every the data in the cell for user to do modification in textbox.
I am facing the problem in capturing the cell data and also bind the pop up to every cell.
