Web Forms :: Getting Data Value From Gridview To A Textbox
Aug 30, 2010
Sorry this might be a very easy question. I am new to VB and programming. I have create a gridview to connect to a SQL database. It returns a single row with 5 columns, including the primary key. I like to create a textbox to obtain the first column and row, that is to display the primary key after the "button" is clicked on. How can I reference this? I tried using expressions in the textbox properties to link the data, but failed.

I have been trying to achieve the following:
1-Allow the user to change the quantity in a textbox i.e // "txtQuantity"
2-capture the newly entered quantity i.e //int integerNewQuantity= int.Parse(textNewQuantity.Text);
3-update the database using the newly entered quantity i.e. //UpdateItem(data,integerNewQuantity)
Problem:1-I have not been able to capture the text i.e. the newly entered quantity i.e. the value entered in the text box "txtQuantity"
2-Hence the database is updated using the existing value and NOT the new value unless I make a constant assignment as below:
textNewQuantity.Text = "2"; When tested the assignment of any number correctly updates the database. see the c# code:
C# code: Version.1
protected void btnUpdate_Click(object sender, EventArgs e)
{
txtItemDescription.Text = txtItemDescription.Text + "from btnUpdate talking.."; [code]....

I have a Gridview with ID "GVSeasonsOfResort" which has selectable rows.
One of the fields in that gridview is RSLinkID which is an ID field of the table from which ths SQLDataSource driving the gridview gets its data.
I have a textbox outside the gridview with ID TxtBxRSLinkID and when I select a row of the Gridview, I want to assign the value of the RSLinkID field of the selected row to the TxtBxRSLinkID.

I have 3 textboxes , 1 dropdown , 1 Button and 1 gridview .
Textboxes ID are :ACode , ADesc , ASeq
DropDown ID is :CPhase
Button ID is :AddRowBTN
GridView ID is :PhasesTempGrid
Now whats the story is ?After adding some data into textboxes , when a user clicks ADDRow BTN , that data gets saved into datatable , then that datatable gets binded to gridview and it shows my textboxes data in it .
What i want to achieve ?In my gridview i am use templateField and inside that template field there are textboxes ( Let the users edit the row without clicking any button ) .
Take an example of dummy data and problem persisting in there :for e.g i put some data in textboxes :ACode = "ABCD"ADesc = "EFGH"ASeq = "HIJK"Then i click Add BTN , it saves the data in datatable and show in gridview , now if i do this in gridview :ACode = "Edited ABCD"ADesc = "Edited EFGH too"ASeq = "WoW There"Then i click Add BTN , it removes the edited record in gridview and shows original data which had came earlier from textboxes :ACode = "ABCD"ADesc = "EFGH"ASeq = "HIJK"I don't want that to be done ... Simple is that user can enter data from textboxes , click the btn to submit into grid then he can edit the data like he want ... data must not get flashed , here's my coding i have done so far :
public void AddNewData()
{
var dt = new DataTable();
if (ViewState["myDatatable"] != null)
{
dt = (DataTable) ViewState["myDatatable"];
}
[CODE]...
here i havent added dropdown combo in gridview but you can do it so that it will save my time (Bind it just the way PhaseDropDown have bind)...

I am having my first go at a nested gridview within a gridview. I have successfully loaded the data and it displays fine. Within the child gridview I have two textboxes that the customer can change. I also have an Save button. When the customer selects the save button the RowCommand for the child grid executes as it should. However I am unable to figure out how to access the two textboxes.
In the past I have got the row index from e.CommandArgument, established the correct GridViewRow using the gridview ID and the row index, and then used findcontrol to get the textbox
int index =
Convert.ToInt32(e.CommandArgument);
GridViewRow row = gvGridView.Rows[index];
TextBox txtName = row.FindControl("txtName")
as TextBox;
But when working within the Child GridView RowCommand event I am unable to figure out how to gain access to the textbox. The child gridview is not recognized.

I have a GridView on an ASP.NET page with a TemplateField column that has a TextBox in the ItemTemplate. I then have a command field which is supposed to pull the text from this TextBox and use it in a SqlCommand running a stored procedure.
Here is my C# code:

When I add a break point to see the values for intID and tbox.Text I get the right ID but the Text for tbox is "".
The mark-up for the two columns I am referencing is
