hi please help me about this problem:
how i can pass value from C# web application into stimulsoft TextBox:
my code :

protected void Page_Load(object sender, EventArgs e)
    {
        this.txt_egample.Text = Decrypt(Request.QueryString["eg"]);
        this.txt_sh_p.Text = Decrypt(Request.QueryString["sh_p"]);
        this.txt_radif_mahkom.Text = Decrypt(Request.QueryString["radif_mah"]);
        this.txt_radif_dad.Text = Decrypt(Request.QueryString["radif_dad"]);
        StiWebViewer1.Visible = true;
        string ConnectionString = ConfigurationManager.ConnectionStrings["Database_ejraConnectionString"].ConnectionString;
        string serverlocation = HttpContext.Current.Server.MapPath(string.Empty);
        StiReport myreport = new StiReport();
        StiText txt = new StiText();
        myreport.Dictionary.Databases.Add(new Stimulsoft.Report.Dictionary.StiSqlDatabase("Coneection", ConnectionString));
        
        txt = (StiText)myreport.GetComponentByName("Text5");
        txt.Text = txt_egample.Text;
        myreport.Load(serverlocation + "\\rep\\Report2.mrt");
        myreport.Dictionary.Variables["sh_par"].Value = txt_sh_p.Text;
        myreport.Dictionary.Variables["rad"].Value = txt_radif_mahkom.Text;
        myreport.Dictionary.Variables["rad_dad"].Value = txt_radif_dad.Text;

我的尝试：



i尝试上面的代码，但此错误显示在此行：

对象引用未设置为对象的实例。 />
txt.Text = txt_egample.Text;

thanks

What I have tried:

i try above code but this error display on this line:
Object reference not set to an instance of an object.
txt.Text = txt_egample.Text;

推荐答案

错误消息表明 txt 或 txt_egample 是 NULL 。



如果这里没有名为Text5的组件，我猜是 txt ：

The error message indicates that either txt or txt_egample is NULL.

I guess it is txt when there is no component named "Text5" here:

txt = (StiText)myreport.GetComponentByName("Text5")

分配后，你也分配给 txt code> StiText 这里的实例，以便永远不会使用此实例：

You are also assigning to txt after you have allocated an StiText instance here so that this instance is never used:

StiText txt = new StiText();

我不知道StimulSoft，但似乎你可以使用

I don't know StimulSoft but it seems you can just use

StiText txt = (StiText)myreport.GetComponentByName("Text5")

并省略分配。但你仍然应该检查 txt 是否有效（非空）。





对不起，我忘了你要设置文字。

有一个 SetText 功能：

and omit the allocation. But you should still check if txt is valid (not empty).


Sorry, I forget that you want to set the text.
There is a SetText function:

StiText txt = (StiText)myreport.GetComponentByName("Text5");
txt.SetText(txt_egample.Text);
