Re: How to insert data into a GridView from the textboxes

19-Oct-09 20:55

Hi all,

I have a Grid view on my page and I need it displayed on Page Load with only the column names. I then need to save data into the Grid view with values for the textboxes after clicking ADD button.

This is what I have but it doesn't do what I want to it to do.

Page_Load:
protected void Page_Load(object sender, EventArgs e)
{
DataTable dt = new DataTable();
this.dgInfoProfile.DataSource = dt;
dgInfoProfile.DataBind();

}

ADD button:
protected void brtAdd_Click(object sender, EventArgs e)
{
try
{
////DataTable dt = new DataTable();
DataRow dr = dt.NewRow();
dr["Full Names"] = txtFirstName3.Text;
dr["Identifying Number"] = txtIdentityNo.Text;
dr["Passport Number"] = txtPassportNo.Text;
dt.Rows.Add(dr);

////Bind GridView Here with this Table
this.dgInfoProfile.DataSource = dt;
dgInfoProfile.DataBind();

}
catch (Exception ex)
{
Response.Write(ex.Message);
}

} Confused | :confused:

if you have any idea on how to get this done, I'd really appreciate your advise.

Thanks.

Better suited in the ASP.NET forum.

I checked the ASP.Net forum first and find that someone has asked the same question and was told that it's not the right forum for such question.

I tried searching on the net but couldn't find how exactly to do it they want I want to.

I really need some help.

What are you getting after clicking ADD button.
Is this ASP.Net application or Windows application?

I get this error: "Column ‘Full Names’ does not belong to table". I'm using ASP.Net application.

Then you should have posted this on ASP.Net forum.
The guy you are talking about, is developing his application in windows forms thats why he is asked to post in windows form.

BTW, Are you definning protype of your DataTable?
Can i see that code?

Here is my code:

Page_Load:
protected void Page_Load(object sender, EventArgs e)
{
DataTable dt = new DataTable();
this.dgInfoProfile.DataSource = dt;
dgInfoProfile.DataBind();

}

ADD button:
protected void brtAdd_Click(object sender, EventArgs e)
{
try
{
////DataTable dt = new DataTable();
DataRow dr = dt.NewRow();
dr["Full Names"] = txtFirstName3.Text;
dr["Identifying Number"] = txtIdentityNo.Text;
dr["Passport Number"] = txtPassportNo.Text;
dt.Rows.Add(dr);

////Bind GridView Here with this Table
this.dgInfoProfile.DataSource = dt;
dgInfoProfile.DataBind();

}
catch (Exception ex)
{
Response.Write(ex.Message);
}

}

Where are you definning columns of DataTable?

"Page_Load" and "Response.Write" -> are ASP.NET.

First : Create your column first, you cannot write to a column, that doesn't exists.
DataTable dt = new DataTable();
dt.Columns.Add(new DataColumn("Full Names"));
dt.Columns.Add(new DataColumn("Identifying Number"));
dt.Columns.Add(new DataColumn("Passport Number"));
this.dgInfoProfile.DataSource = dt;
dgInfoProfile.DataBind();

Re: How to insert data into a GridView from the textboxes

I've created the header columns in my design like this:

<asp:gridview id="dgInfoProfile" runat="server">
<columns>
<asp:boundfield headertext="Full Names">
<asp:boundfield headertext="Identifying Number">
<asp:boundfield headertext="Passort Number">

Didn't know that I have to define the columns in the code behind again.

That's why, ask in ASP.NET forum, because what you've done is working in WinForm.

Thanks so much, really appreciate your help.
I'll ask in ASP.Net forum and also search on the net since I don't have some books at present.

Ofcourse you have to, these are columns of GridView, you has to define colums of DataTable then only you can create a DataRow.

I have a better suggestion.
Stop what you are doing, read a book first which will explain you about databindings with GridView or search and read some article(you'll find many on this site itself). I am sure, you don't have much knowledge about this.

For this you have to use TemplateFields in GridView columns collection. Smile | :)

Thanks a lot. For more info I'll acquire in ASP.Net forum.

Hi all,

Hope this is in the correct forum. I have an issue with some work I am involved in. We have a flat file we are loading into an MSSQL database which is failing on the insert because the original flat file contains suspect data. Invalid dates or values etc. We are using SSIS to load this data. Can someone tell me if it is possible to exception these records easily.

requirements are
- to identify the number of records with the problem
- to identify these records
- to manage the issues which error

I am a project manager and do not want the wool pulled over my eyes. I am familar with C# and SQL server but have only seen SSIS over a shoulder of a developer.

I believe this would be a simple change and would be a matter of minutes to resolve. I am currently being led to believe it is hard.

Thanks all

Its not really the right forum, this is for question to do with C# coding.

Happy to answer your question though.

NOTHING takes minutes to resolve - you should know that as a PM. Development, testing, deployment, bugfixing - a time estimate should take all of this (and more) into account.

Anything to do with SSIS is a royal PITA, nothing is quick and easy.

My best suggestion for this problem is to bulk load your text file into an empty table, and do the data clensing thereafter. All this can be achived easily with SSIS, but certainly not in a matter of minutes.

Hi,

Thanks for replying. So you are saying that you cannot ignore errors easily in SSIS and count them. I C++ or java or C# this would be a try, carch cout which is a matter of minutes. I had hoped that microsoft would have made this easier.

Not knowing how your SSIS package is constructed makes answering this harder.

For a Data Flow task (which is the most likely thing you're using), you can often pipe errored rows to a separate file.

Its still not "minutes" work though Wink | ;)
